Question

Please help!! I don’t understand this

Answer 1

Theorem: pythagorean

Equation:

`{90}^(2) + {h}^(2) = {180}^(2)`
Solving:

`{h}^(2) = 24300`

`h = 155.9`

Answer 2

You have to assume that the height is a standard definition of height. It meets the base at a right angle.

That said, you have a right angle triangle meeting the base at 90o and at the midpoint of the base. The midpoint would be at 90 meters.

Now you can solve the missing side of the right tringle

c = 180
b = 90
h =????

h^2 + b^2 = c^2
h^2 + 90^2 = 180^2
h^2 + 8100 = 32400
h^2 = 32400 - 8100
h^2 = 24300
h = 155.9
