A set of stairs inclines at a 110 degree angle. A support beam is going to be constructed under the stairs. What angle measure does the support need to have?

Question

A set of stairs inclines a t a 110 degree angle.  A support beam is going to be constructed under the stairs. What angle measure does the support need to have?

Answer 1

The question is not clear how the support beam is going to constructed under the stairs,but if the support beam is a right angle to the 110° angle, then it will form a right triangle with angles of 90°, 70°, 20°, where 70° is from 110°- 90° and 20° is from 90° - 70°.

 

 

Therefore, the angle measure the support need to have is 20°.
