Answer:

<h2>135 ft²</h2><h2 />

Step-by-step explanation:

see attached image

<u>shaded area = total area (1)  - unshaded triangular area (2)</u>

1.  area of a trapezoid = (a + b) * h/2

   where a = 8,  b = 18,  h = 15

   Area of trapezoid = (8 + 18) * 15/2 = 195 ft²

2.  Area of unshaded triangle = 1/2 (8) 15 = 60 ft²

shaded area =  195 - 60 = 135 ft²

Find the indicated side of the<br> right triangle.
Advocard [28]

Answer:

?=9

Step-by-step explanation:

We have a special right triangle, the 45-45-90 triangle.

In a 45-45-90 triangle, the side lengths are x, and the hypotenuse is x√2.

Since we know that the side length is 9, this means that:

x=9\\\text{Hypotenuse}=x\sqrt2\\\text{Hypotenuse}=9\sqrt2

The ? is 9.
