Triangle ABC is shown with its incenter at D. The inscribed circle's radius measures 2 units. The length of AB is 9 units. The length of BC is 10 units. The length of AC is 17 units.
What is the area of triangle ACD?
What is the area of triangle ABC?
The area of triangle ACD and ABC are 17 and 46.75 square units respectively
How to find the area of a triangleThe formula for finding the area of a triangle is expressed as:
A = 0.5bh
where:
b is the base
h is the height
Area of the triangle ACD = 0.5DE * AC
Area of the triangle ACD = 0.5(2)(17)
Area of the triangle ACD = 17 square units
For the triangle ABC
Area = 0.5(BE)(AC)
Area= 0.5(5.5)(17)
Area = 46.75square units
Hence the area of triangle ACD and ABC are 17 and 46.75 square units respeectively

The amount of money spent at a gas station varies directly with the number of gallons purchased. When 15.5 gallons of gas was purchased , the cost was $48.67. What is the cost for 9 gallons of gas?
Answer:
$28.26
Step-by-step explanation:
In order to find out how much each gallon of gas cost, you need to divide the $48.67 by the 15.5 gallons. This would equal 3.14 So the cost for one gallon is $3.14
Then you would need to multiply this number by the 9 gallons to get the price. Which would equal $28.26

Write an equation of a line through (5,6) and perpendicular to the line through (4,8) and (-2,-18). please help, will mark brainliest. You also get 10 points
Answer:
y = 4 1/3x+ 6
Step-by-step explanation:
Step 1. The slope-intercept form is given as y=mx+b where m is the slope and b is the y-intercept. The y-intercept occurs at x=0 or point (0,b).
-18 -8 / -2 - 4 = -26 / -6 = 4 1/3 perp = - 4 1/3 = y=4 1/3 x+b
Step 2. -18 -8 / -2 - 4 = -26 / -6 = 4 1/3 perp = - 4 1/3 is a vertical line or parallel to the y-axis. So a line perpendicular to x= 4 1/3 is a horizontal line parallel to the x-axis.
Step 3. Therefore y= 4 1/3 is a horizontal line parallel to the x-axis. Now, the line needs to pass through point (5,6) or x=5 and y=6. Then, y=b=6 or y=6 is the equation of the line. but then x = 4 1/3 so y = 4 1/3x + 6
Step 4. ANSWER: The equation is y = 4 1/3x+ 6 where slope m=4 1/3 and y intercept b=6.
Use the Law of Sines to solve (if possible) the triangle. If two solutions exist, find both. Round your answers to two decimal places. (If not possible, enter IMPOSSIBLE.) A = 72°, a = 34, b = 21
Answer:
Given: A = 72°, a = 34, b = 21
Calculated: B = 35.97°, C = 72.03°, c = 34.00
Step-by-step explanation:
[tex] \dfrac{\sin A}{a} = \dfrac{\sin B}{b} [/tex]
[tex] \dfrac{\sin 72^\circ}{34} = \dfrac{\sin B}{21} [/tex]
[tex] \sin B = \dfrac{21\sin 72^\circ}{34} [/tex]
[tex] \sin B = 0.5874 [/tex]
[tex] B = \sin^{-1} 0.5874 [/tex]
[tex] B = 35.97^\circ [/tex]
C = 180° - 72° - 35.97°
C = 72.03°
[tex] \dfrac{\sin A}{a} = \dfrac{\sin C}{c} [/tex]
[tex] \dfrac{\sin 72^\circ}{34} = \dfrac{\sin 72.03^\circ}{c} [/tex]
[tex]c = \dfrac{\sin 72.03^\circ \times 34}{\sin 72^\circ}[/tex]
[tex] c = 34.00 [/tex]
Given: A = 72°, a = 34, b = 21
Calculated: B = 35.97°, C = 72.03°, c = 34.00
Answer:
[tex]B\approx35.97^\circ\\C\approx72.03^\circ\\c\approx34[/tex]
Step-by-step explanation:
Law of Sines
[tex]\frac{sinA}{a}=\frac{sinB}{b}=\frac{sinC}{c}[/tex]
Given information
[tex]A=72^\circ\\a=34\\b=21[/tex]
Check if solutions exist
As [tex]A=72^\circ < 90^\circ[/tex] and that [tex]a > b\rightarrow 34 > 21[/tex], then there exists only one possible triangle by the Ambiguous Case
Solve the triangle
[tex]\frac{sin(72^\circ)}{34}=\frac{sin(B)}{21}\\ \\ 21sin(72^\circ)=34sin(B)\\\\\frac{21sin(72^\circ)}{34}=sin(B)\\ \\B=sin^{-1}(\frac{21sin(72^\circ)}{34})\\ \\B=35.97394255^\circ\approx35.97^\circ[/tex]
[tex]A+B+C=180^\circ\\\\72^\circ+35.97394255^\circ+C=180^\circ\\\\107.97394255^\circ+C=180^\circ\\\\C=72.02605745^\circ\approx72.03^\circ[/tex]
[tex]\frac{sin(72^\circ)}{34}=\frac{sin(72.02605745^\circ)}{c}\\\\c*sin(72^\circ)=34sin(72.02605745^\circ)\\\\c=\frac{34sin(72.02605745^\circ)}{sin(72^\circ)}\\ \\c=34.00502065\approx34[/tex]

Answer: x=-3
Step-by-step explanation:
In this question, they simply want you to find a pair of x and y-coordinates that would be valid in this equation.
We can take a random number for x, like, say, 3.
y = 2x + 6
y = 2(3) + 6
y = 6 + 6
y = 12
Since giving the value of 3 to x results in y being 12, we can safely say that the coordinates (3, 12) would be valid in this equation. Therefore:
(12) = 2(3) + 6
Let me know if you need me to explain anything.

find the probability of the indicated event if P(E)=.20 and P(F)=.45.
Find P(E and F) if P(E or F)=.45
There are three section here
First section is the event of only E, the second is the event of only F, and the third is the event of the overlap of E and F
E or F means the total unit of events. Which is (only E)+(only F)-(E and F)
Using substitution we get 45=20+45-(E and F)
solving the equation
E and F=65-45
E and F=20
Therefore, P(E and F) is 20

Dilate rectangle H J K L by a scale factor of 2 about the origin, then reflect it across the x -axis. Dilate rectangle H J K L by a scale factor of 1 2 about the origin, then translate it 12 units down. Dilate rectangle H J K L by a scale factor of 1 2 about the origin, then translate it 12 units down. Dilate rectangle H J K L by a scale factor of 1 2 about the origin, then reflect it across the x -axis.
The sequence of transformations involves reflection, translation, dilation and reflection
How to determine the sequence of transformations?The question is incomplete;
So, I will give a general explanation
For the two rectangles are similar shapes, then the corresponding sides of the shapes must be similar.
If the rectangles do not have the same size, then the scale ratio of the sides of the rectangles must be the same
if the rectangles have the same size, then the rectangles must fit perfectly on one another

Answer:
[tex]x=\frac{324}{5}[/tex]
Step-by-step explanation:
Given the following question:
[tex]\sqrt{5x} -7-3=8[/tex]
To find the answer we are going to use inverse of operations to isolate the variable x, doing this we can then find the value of the variable and then have our answer.
[tex]\sqrt{5x} -7-3=8[/tex]
[tex]-7-3=-10[/tex]
[tex]\sqrt{5x} -10=8[/tex]
