Help ASAP show the work, no links pleaseee

Answer 1

3x+2(x+20)=180
3x+2x+40=180
5x=180-40
5x=140
x=28

Answer 2

x = 28

Explanation:

AB= AC

∠B = ∠C {Angles opposite to equal sides are equal}

∠A + ∠B + ∠C = 180 {angle sum property}

3x + x + 20 + x + 20 = 180 {Combine like terms}

3x +x +x + 20 + 20 = 180

5x + 40 = 180 {subtract 40 from both sides}

5x = 180 - 40

5x = 140 {divide both sides by 5}

x = 140/5

x = 28
