Question

NEED HELP ASAP!!!!! PLEASE HELP ME

Answer 1

m∠A = 40°

m∠B = 70°

Explanation:

The sum of angles in a triangle is 180°.

x + 49 + x + 79 + 70 = 180

2x + 198 = 180

2x = 180 - 198

= -18

x = -18 ÷ 2

x = -9

m∠A = x + 49

= (-9) + 49

m∠A = 40°

m∠B = x + 79

= (-9) + 79

m∠B = 70°

Answer 2

ANSWER

X = -9

EXPLANATION: you subtract 180 - 70 giving you 110

Equation set up: x + 49 + x + 79 = 110
