A:
The angle of 80 degrees is the same angle as the one with the equation. That equation has to equal 80 somehow. ------------------------------------------ 80 - 20 (from equation) = 60 60 ÷ 2 (also from equation) = 30 -------------------------------------------- x = 30 To make sure plug it in (2 x 30)+ 20 60 + 20 = 80 --------------- x should equal 30
