if a point a device line segment a b of length 10 centimetre internally In the ratio 2:3 then find the length of a d
Given:
Consider a point d divides line segment ab of length 10 centimetre internally in the ratio 2:3.
To find:
The length of ad.
Solution:
If a point d divides line segment ab internally in the ratio 2:3, then the length of ad and db are 2x and 3x receptively.
We know that,
[tex]ab=ad+db[/tex]
Length of the segment ab is 10 cm.
[tex]10=2x+3x[/tex]
[tex]10=5x[/tex]
Divide both sides by 5.
[tex]2=x[/tex]
Now,
[tex]ad=2x[/tex]
[tex]ad=2(2)[/tex]
[tex]ad=4[/tex]
Therefore, the length of segment ad is 4 centimetres.
160 bananas;20%decrease
Answer:
128 banana's... I would work it all out for u but the teacher just came in my room and had a go
Answer: 128
Step-by-step explanation:
Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
20% = 20/100 = 20 ÷ 100 = 0.2.
100% = 100/100 = 100 ÷ 100 = 1.

11 Tenths
Step-by-step explanation:
Withouth the tenths, the bottom number would be 1.05. So we need 1.10 or 11 more. 10 tenths is one whole plus the 1 tenth we need to put in the tenths place.

Answer:
[tex]7^{12}[/tex]
Step-by-step explanation:
When you divide two numbers that have exponents and have the same base, just subtract the exponents. In this case, 7 is the base of both the dividend and the divisor. So, simply subtract 14 - 2 to get 12. The final answer is [tex]7^{12}[/tex].

Given: Quadrilateral ABCD is a kite. Prove: ΔAED ≅ ΔCED Kite A B C D is shown. Diagonals are drawn from point A to point C and from point B to point D and intersect at point E. It is given that quadrilateral ABCD is a kite. We know that AD ≅ CD by the definition of . By the kite diagonal theorem, AC is to BD This means that angles AED and CED are right angles. We also see that ED ≅ ED by the property. Therefore, we have that ΔAED ≅ ΔCED by .
Answer:
1. kite 2. perpendiclular 3. reflective 4. HL
Step-by-step explanation:
I hope this helps :)
Answer:
We know that AD ≅ CD by the definition of kite. By the kite diagonal theorem, AC is perpendicular to BD. This means that angles AED and CED are right angles. We also see that ED ≅ ED by the reflexive property. Therefore, we have that ΔAED ≅ ΔCED by HL.
Step-by-step explanation:
We know that AD ≅ CD by the definition of kite.
- adjacent sides in a kite are congruent
By the kite diagonal theorem, AC is perpendicular to BD.
- the kite diagonal theorem states that diagonals of a kite form right angles because they are perpendicular to each other.
We also see that ED ≅ ED by the reflexive property.
- any side or angle congruent to itself is identified by the reflexive property
Therefore, we have that ΔAED ≅ ΔCED by HL.
- the triangles formed are all right triangles, so we can they that the two triangles are congruent to each other by the Hypotenuse Leg theorem.

Answer:
1. Complementary Angles.
2. x=60°
Step-by-step explanation:
Part 1:
*Note: A complementary angle is when the sum of two angles equal 90 degrees. A Supplementary angle is when the sum of 2 angles equals 180 degrees.
In this instance, the 2 angles equal 90 degrees, as indicarted by the box on the angle. Therefore, the the angles are complentary.
Part 2:
1. Since we know that the sum of the two angles (x-30 and x) is 90 degrees, we can write an equation which says: (x-30) + x=90.
2. Then we'd simplify the equation by adding the like variables, and adding 30 to both sides:
2x=120
3. Now we will divide both sides by 2
[tex]\frac{2}{2} x=\frac{120}{2} \\x=60[/tex]
4. As a result, we get x=60, now label your answer with the degree sign, and enjoy your answer.

Answer:
x = 6
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let the third side be x , then
x² + 8² = 10²
x² + 64 = 100 ( subtract 64 from both sides )
x² = 36 ( take the square root of both sides )
x = [tex]\sqrt{36}[/tex] = 6
Answer:
6
Step-by-step explanation
Ordered triples only apply to right triangles
3,4,5 is an ordered triple
multiply (3,4,5) by 2 and you get (6,8,10)
the 2 other side lengths are 8 and the hypotenuse is 10 then the other side length is 6.
-------------------
That is just a way to do it quickly and it does not always apply.
the formula for Pythagorean and theorem is a^2+b^2=c^2
a=leg of the triangle
b=other leg of teh triangle
c=hypotenuse(longest leg)
as we can see here 10 is the longest so it is the hypotenuse.
So then we can assume that 8 is a leg of the triangle
so we insert that into the equation
a^2+8^2=10^2
subtract 8^2 from both sides
a^2=10^2-8^2
a^2=100-64
a^2=36
square root both sides
a=√(36)
a=6
Hope that helps :)

Answer:
27.4
Step-by-step explanation:
Use your calculator for this.
Remember, use SOH CAH TOA
We have an opposite (O) and an adjacent side (A), so we use SINE
sin(41)=18/X......following?
Now, solve for X by multiplying both sides by X......sin(41)(X)=18
Then, divide both sides by sin(41).
Type into your calculator: 18/sin(41), and you'll get 27.44. Round to the nearest tenth, or 27.4!
Answer:
x = 11.8
Step-by-step explanation:
sine = [tex]\frac{opposite}{hypotenuse}[/tex]
⇒ sine 41 = [tex]\frac{18}{x}[/tex]
⇒ 0.656 = [tex]\frac{18}{x}[/tex]
multiply 18 on both sides:
⇒ 0.656 x 18 = [tex]\frac{18}{x}[/tex] x 18
⇒ 11.808 = x
round to the nearest tenth:
⇒ 11.808 = 11.8
Write an equation in standard form for the line.
Slope is 3, and (1, 6) is on the line.
Answer:
Step-by-step explanation:
m = 3
(1 , 6)
y - y1 = m(x -x1)
y - 6 = 3(x - 1)
y - 6 = 3x - 3
y = 3x - 3 + 6
y = 3x +3
Standard form:
-3x + y - 3 = 0

write the equation for this line
If this is for slope-intercept, the equation is: y = 3x + 1
To find the slope, you would find the rise over run ( [tex]\frac{rise}{run}[/tex] ). So, you would start where the graph intersect at the y-axis, which is 1. You would go up 3 times, and right 1 time. So, [tex]\frac{3}{1}[/tex], or 3, would be your slope. To find the y-intercept, you would need to find where the graph intersects at the y-axis, which is 1, so it would be your y-intercept. Plug them into the y = mx + b formula and the answer is y = 3x + 1.
