Question

Find the measure of angle x.

Answer 1

x°+x°+40°=180°

2x°=180°-40°

2x°=140°

x°=140°

2

x°=70°

x°=70°

therefore,

x=180°-70°

x°=110°

Answer 2

Answer: 110 degrees

Since the 2 unknown angles in the triangle are equal you do (180-40)/2 to find what they are equal to. (It's equal to 70) Now that you have the answer for the two angles, now you can subtract 70 from 180 which gives you 110 degrees and that's your answer
