Answer:
Step-by-step explanation:
we are given that one angle is 40 degrees. The right angle below that is 90 degrees. Right angles will always equal 90 degrees. with the two angles how do we solve. Triangles no matter what will always be 180 degrees so,
40+90+x=180
130+x=180
-130 -130
x=50 degrees
Alright, lets get started.
Please refer the attached diagram.
The roof will make a right angle triangle.
Thy hypotenuse of the triangle will be the length of roof that is given 44 feet.
The opposite side will be height of roof that is 10 feet.
Lets suppose roof makes x degree angle from horizontal.
So, we know,
sin x = opposite / hypotenuse
sin x = 10 / 44
sin x = 0.2272727272
Taking inverse on both sides
sin -1 (sin x) = sin -1 (0.2272727272)
x = sin -1 (0.2272727272)
x = 13.13 degrees
So the angle that roof makes with horizontal is 13.1 degrees (option b) : Answer
