Find the area of the polygon

Step-by-step explanation:

So the area of a cube is a²

This means that:

2² = 4cm²

So the area of a triangle is (b*h)/2

This means that:

(3*2)/2 =

6/2 = 3cm²

4cm² + 3cm² = 7cm²

Overall area is 7cm².

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
