Question

The vertical studs are parallel to each other, and the braces are parallel to each other.If the measure of Z1 in the diagram is 105°, what is the measure, in degrees, of 22?

Answer 1

SOLUTION:

Since angle 1 is 105, let the angle adjacent to the angle 1 be called p.

So, P + 105 = 180 (sum of angles on a straight line)

P = 180 - 105

p = 75

Then the angle 2, is an alternate angle to P, so Angle 2 is 75
