Answer 1

Answer:

1. x=74

2. x=86

Step-by-step explanation:

1. the sum of interior angles in a triangle is 180 degrees

81 + 25 + x = 180

106 + x = 180

x = 74

2. once again the sum of interior angles in a triangle is 180 degrees so add up the terms and set them equal to 180

x + x-35 + 43 = 180

add up like terms (x and x, -35 and 43)

2x +8 = 180

2x = 172

x = 86
