Question

<1 and <2 are vertical angles.  If m<1 = (6x+11)and m<2=(10x-9) find m<1?

Answer

Vertical angles are the angles opposite each other when two lines cross. They are always equal.

Given: m<1 = (6x+11) and m<2=(10x-9)

6x + 11 = 10x - 9  The rule is you can do any valid operation on both sides of an equation and it will still be equal. Subtract 11.

6x = 10x - 20  Subtract 10x.

-4x = -20  Divide by -4.

x = 5

m<1 = (6x+11) = 41  <--  ANSWER
