In the triangle above, the sum of the angles is 180
We have been given 2 of the angles of the triangle which are 57 and 61.
Lets name the third angle x

Therefore, x = 180 -(57+61) = 180 - 118 = 62(Option D)

Should be D - 62

Sum of interior angles of a triangle = 180

57 + 61 + x = 180

118 + x = 180

x = 180 - 118 = 62

All triangles sum to 180 degrees. Thus:

57 + 61 + x = 180

x + 118 = 180

x = 62

Answer: D
