Answer:D. 36 m

Step-by-step explanation: Use the Pythagorean Theorem, which is a^2 + b^2 = c^2 to find the missing side. C is the hypotenuse. Plug in the numbers.

15^2 + b^2 = 39^2

Simplify.

225 + b^2 = 1521

Subtract 225 from each side.

b^2 = 1296

Square root each side to isolate b.

b = 36

The height of the support beam is 36 m.
