Step-by-step explanation:

1.) x + 37 + x + 67 + 90 = 180

combine like terms

2x +194 = 180

subtract 194 both sides

2x = -14

x = -7

2.) 63 + 86 = x

x = 149

Answer:

1. (x+37) + (x+67) + 90° = 180°

=> x + x + 37 + 67 + 90 = 180

=> 2x +194 = 180

=> 2x = 180 –194

=> 2x = –14

=> x = –14/2

=> x = –7

2. [The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles. ]

x = 63° + 86°

=> x = 149°
