Arturo is designing a bridge for science class using parallel supports for the top and bottom beam. Determine m angle 2 if m angle 1 equals 60 degrees

Question

I don’t know how to solve this, so we have to make an equation, or add 180 and subtract 60?

Answer 1

You need to draw a figure of what you want.

I suspect what you have is an isosceles trapezoid with 60 degrees as the angle between the bottom beam and the support. Then what you want to know is the angle between the support and the upper beam, which as you suggested is 180 - 60 = 120.
