Answer:

measure of angle 1: 102 degrees

measure of angle 2: 78 degrees

Step-by-step explanation:

angle 1 + angle 2 = 180 degrees because they are a linear pair.

(x+63)+2x=180              angle1  x+63 or (39)+63                angle2 2x or 2(39)

3x+63=180                                  39+63= 102                          2 x 39 = 78

     -63   -63

3x=177

/3   /3

x=39

Hope this helps :D

Answer:

The measure of angle 1 is: 102

The measure of angle 2 is: 78

Step-by-step explanation:

  1. Write an equation modeling the situation: x+63+2x=180 (It equals to 180 because of the straight line on the bottom)
  2. Add like terms: 3x+63=180
  3. Subtract 63 from both sides: 3x=117
  4. Now divide 117 by 3 to get: x=39
  5. Now that you know what x is, substitute 39 where the "x"s are.

I hope this helps!!
