Answer:

1. T =34

2.143 =exterior A

Step-by-step explanation:

The sum of the angles in a triangle is 180 degrees

T+H+E =180

T + 107+39 = 180

Combine like terms

T +146 = 180

Subtract 146 from each side

T +146-146 = 180-146

T =34

The exterior angle is the sum of the opposite interior angles in a triangle.

B+T =exterior A

66 +77 = exterior A

143 =exterior A
