Answer:
height = 13.75 feet
Step-by-step explanation:
use the Pythagorean theorem
hypotenuse^2 =base^2 + height^2
15^2 = 6^2+height^2
225 = 36 + height^2
189 = height^2
height = 13.75 feet
Answer:
d. 36
Step-by-step explanation:
you would create a proportion of 11.5 over 34.5 then you would make it equal to 12 over x. Then cross multiply 34.5 by 12 to get 414. then you would divide this by 11.5 to get 36
