Question

Determine the measure of the missing angle.

Answer 1

Step-by-step explanation:

65° + 57° + x = 180° ( the sum of angle of triangle is 180° )

122° + x = 180°

x = 180° - 122°

x = 58°

hence the answer is 58°....

Answer 2

Answer:

58 degrees

Step-by-step explanation:

Sum of angles in a triangle is 180 degrees

180 = 65 + 57 + x

180 = 122 +x

x =180 -122

x = 58
