Question

PLEADE HELP I WILL MARK YOU AS BRAINEIST

Answer 1

83

Explanation:

(3a+8)+(60-a)+(4a-38)=180

combine like terms, 6a+30=180

inverse operation to isolate the variable, 6a=150

divide six on both sides, a=25

replace a in every expression, 3(25)+8=83

60-25=35

4(25)-38=62

83 is biggest out of the three, therefore 83 is the answer.

Answer 2

83

Explanation:

a = 25

The biggest angle is (3a+8) = 83
