Question

I need help setting up a problem on my homework (problem will be in COMMENTS)

Answer 1

Whats the problem

Answer 2

well....the interior angles of a triangle equal 180 degrees

2x + (x + 30) + x = 180
4x + 30 = 180
4x = 180 - 30
4x = 150
x = 150/4
x = 37.5

2x = 2(37.5) = 75 degrees
x + 30 = 37.5 + 30 = 67.5 degrees

180 - (75 + 67.5) = 180 - 142.5 = 37.5 degrees

so I believe your 3 angles are : 75 degrees, 67.5 degrees, and 37.5 degrees with x being 37.5

you might better get a second opinion on this...geometry is not my best subject
