Answer:
Bottom part = 10 * 12 = 120 square centimeters
Top part 8 * 6 = 48 square centimeters
Total Area = 168 square centimeters
Step-by-step explanation:
If we discuss this as if it is a triangle then the "rise" is the vertical side and the "run" is the adjacent side.
So the ratio of the rise to the run is 8 / 15 which equals

To find the angle of this roof pitch we look up the arc tangent of

and we find that is 28.072 Degrees

The appropriate choice is ...
A. 3 radians
_____
Arc length (s) is given in terms of radius (r) and central angle (θ) in radians by the formula
s = rθ
When you substitute your given information, you have
3r = rθ
Dividing by r gives
θ = 3 . . . . . . . radians
The figure is called an Acute Triangle. The Area is 199.96 centimeters squared. The perimeter (or circumference) is 68.
