Answer: 5.6ft
Step-by-step explanation:
30/2=15 <— Base
Pythagoras’ theorem: a^2 + b^2 = c^2
Call the base a, height b, and hypotenuse (longest side) c
Rearrange to find b: b^2 = c^2 - a^2
Substitute in the values: b^2 = 16^2 - 15^2
Simplify: b^2 = 256 - 225 = 31
b = square root of 31 = 5.6 ft to the nearest tenth of a foot
Hope this helps :)
