Answer:
area of rectangle = 120 cm²
area of triangle = 24 cm²
area of trapezoid = 144 cm²
Step-by-step explanation:
12 * 10 = 120
12 * 4 = 48
48 / 2
add the triangle and rectangle area together
7 / 12 = 0.583333333
Divide them all to see which one equals 0.583333333.
A.
8 / 13 = 0.615384615
B.
10 / 15 = 0.666666667
C.
14 / 19 = 0.736842105
D.
21 / 36 = 0.583333333
Therefore, your answer is D.
Answer:
52.2
Step-by-step explanation:
Light reflects off a mirror at the same angle it hits it at (as shown in the image). Since both triangles are right triangles, we can say they are similar by AA similarity.
Since they're similar, we can write a proportion.
HT / TV = JS / SV
Plugging in values:
5.8 / 4 = JS / 36
JS = 52.2
The wall is 52.2 feet tall.
The answer you just put is correct
