The sum of the measures of the interior angles of the triangle is 180°. Write and solve an equation to find the value of the variable.

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
