Question

<A and <B are supplementary angles. If m<A= (8x-25)° and m <B=(7x-5)° , then find the measure of <B. answer asap?​

Answer 1

Explanation:

27

Answer 2

Explanation:

∠A + ∠B = 180 {supplementary angles}

8x - 25 + 7x - 5 = 180 {bring the like terms together}

8x + 7x - 25 - 5 = 180 {add the like terms}

15x - 30 = 180 {add 30 to both the side}

15x = 180 +30

15x = 210 {divide both sides by 15}

15x/15 = 210/15

x = 14

∠B = 7x - 5 = 7*14 - 5

= 98 - 5

∠B = 93°
