Find AE if AB=12, AC=16, and ED=5.
Answer:
the ratio is 12:16=3/4
So AE:5+AE=3/4
4AE=15+3AE
AE=15
Step-by-step explanation:
The length of the line segment AE is 15 units.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points.
Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know, In a triangle if one segment is parallel to one side of a triangle divides the other two sides in the ratio of their corresponding lengths.
Given, AB = 12, AC = 16 and ED = 5, hence BC = AC - AB = 4.
Therefore, AB/BC = AE/ED.
12/4 = AE/5.
4AE = 60.
AE = 15 units.

The combined area of a pair of congruent rectangles can be represented, in square units, by the expression 18y^2-818y 2 −8. The length and side of each rectangle can be represented as a difference of squares. What is the perimeter of one of the rectangles?
Answer:
[tex]Perimeter = 12y[/tex]
Step-by-step explanation:
Given
[tex]Area = 18y^2 - 8[/tex] -- two rectangles
Required
Determine the perimeter of one of the rectangles
First, calculate the area (A) of 1 rectangle
[tex]A =\frac{1}{2}Area[/tex]
[tex]A =\frac{1}{2}(18y^2 - 8)[/tex]
[tex]A =9y^2 - 4[/tex]
Express as difference of two squares
[tex]A =(3y - 2)(3y+2)[/tex]
Area is calculated as:
[tex]A = Length * Width[/tex]
So, by comparison:
[tex]Length = 3y - 2[/tex]
[tex]Width = 3y + 2[/tex]
The perimeter is:
[tex]Perimeter = 2 *(Length + Width)[/tex]
[tex]Perimeter = 2 *(3y-2+3y+2)[/tex]
Collect Like Terms
[tex]Perimeter = 2 *(3y+3y-2+2)[/tex]
[tex]Perimeter = 2 *(6y)[/tex]
[tex]Perimeter = 12y[/tex]

Find the measure of
Answer:
19 degrees.
Step-by-step explanation:
First solve the angles in the top triangle:
FHG = 180 - 135 = 45 (angles on a straight line = 180)
FGH = 180 - 105 = 75 (angles on a straight line = 180)
Using these we get HFG = 180 - 45 - 75 = 60 (angles in a triangle = 180)
Then because HFG is directly opposite DFC on the crossed lines, we know they are equal: DFC = 60
FDC = 180 - 119 = 61 (anges on a straight line = 180)
Now if we label ABC (the target angle) as x then we known ACB = 180 - 40 - x.
With this we know FCD = 180 - ACB = 180 - (180 - 40 - x) = 40 + x (angles on a straight line).
Finally using the FDC triangle we have 40 + x + 60 + 61 = 180 so x = 180 - 40 - 60 - 61 = 19 degrees.
Solve the equation. Check your solution and show all your work.

Answer:
t = 19 1/4
Step-by-step explanation:
24 1/2 = t + 5 1/4
49/2 = t + 21/4
t + 21/4 = 49/2
t = 49/2 - 21/4
t = 98/4 - 21/4
t = 77/4
t = 19 1/4
Find the measure of the indicated angle to the nearest degree
A) 18°
C) 48°
B) 42°
D) 26°
Answer:
The answer is option C
Step-by-step explanation:
To find the indicated angle we use sine
sin ∅ = opposite / hypotenuse
From the question
The opposite is 37
The hypotenuse is 41
So we have
sin ? = 37/41
? = sin-¹ 37/41
? = 64.4805
? = 64° to the nearest degree

Homework: Compound Probability (Without Replacement)
2.) There are three nickels, four dimes, and four quarters in your pocket. You randomly pick three coins and place them on a counter. The first coin is a nickel, the second is a dime, and the third is a quarter.
3/110, 8/165, 1/64, 10/273
3.) A box of chocolates contains four milk chocolates and six dark chocolates. You randomly pick a chocolate and eat it. Then you randomly pick another piece. The first piece is milk chocolate and the second piece is dark chocolate.
4/15, 5/18, 5/22, 3/110
Answer:
For number 2: 8/165
Step-by-step explanation:
The total number of coins = 11 ( 3 + 4 + 4 = 11).
The probability of picking a nickel first = 3/11 ( 4 nickels out of 11 total).
The probability of picking a dime second = 4/10 = 2/5 ( 3 dimes out of 10 coins left).
The probability of picking the third coin as a quarter = 4/9 ( 3 quarters out of 9 coins left).
I don't know the other problem, sorry.

Step-by-step explanation:
In a parallelogram AO and OC are equal. Therefore you should set up the equation 3x-4=8. When you add 4 to both sides you get 3x=12. When you divide both sides by 3 you get x=4
4 (4b + 3) + 2b = 3 (b - 11)

What is similar triangle?Triangles are said to be similar triangle" if they are proportional equality corresponding sides and equal pair of corresponding angles".
According to the question,
∠C =∠E, ∠B=∠D and ∠A=∠A this implies given triangle is inscribed similar right angle triangle.
ΔCBA ≅ ΔEDA [Similar triangle]
Properties of similar triangle: [tex]\frac{CB}{ED} = \frac{BA}{DA}[/tex]
[tex]\frac{6}{7}=\frac{7}{7+x}[/tex]
[tex]6(7+x)=49[/tex]
