5x-20 = x+50 4x = 70, x = 17.5 So these angles are 67.5 BED = 180 - 67.5 = 112.5 degrees

1. the measure would be 85 because angle a and 35 have to equal the exterior angle (120) 2. well 65 + x have to equal 3x-5, so you set up the equation 65+x=3x-5. you would subtract the x from both sides and get 65=x-5 then add 5 to both sides and get x=70. 4. angle 1 would be 30 because vertical angles are congruent. those...
