1 and 2 are vertical angles. if m1 = (17x+1) and m2 = (20x-14) find m2

Answer 1

Because they told you that 1 and 2 are vertical angles, we know that their measurements are equivalent. Therefore, we can set the two measurements equal to each other as our first step, and solve for x.

17x+1=20x-14

15=3x

x=5

Now that we have x, we can substitute that into the expression for the measurement of angle 2.

20x-14

20(5)-14

100-14

86

So, the measure of angle 2 is 86°. Hope this helps!
