Please help with this geometry math problem!

∠8 * 4 = ∠7 (1)

∠8 + ∠7 = 180 (2)

Taking the value of ∠7 from (1) and using it in (2):

∠7 = 4 * ∠8

∠8 + ∠7 = 180

∠8 + (4 * ∠8) = 180

∠8 + 4∠8 = 180

5∠8 = 180

∠8 = 36° (3)

Using the value of ∠8 from (3) in (2):

∠8 + ∠7 = 180

36 + ∠7 = 180

∠7 = 144°       and       ∠8 = 36°

22.83 repeating

step-by-step explanation:

137 ÷ 6 is 22.8333333 therefore we understand that 3 is repeating.
