Angle Terminology with Equations

Question

∠1 and angle, 2∠2 are vertical angles. If mangle, 1, equals, left bracket, 2, x, minus, 26, right bracket, degrees∠1=(2x−26)∘ and mangle, 2, equals, left bracket, x, plus, 25, right bracket, degrees∠2=(x+25)∘, then find the value of x.

Answer 1

vertical angles always equal each other

2x-26=x+25

x=51
