Find the value of x and y
Aleks04 [339]

Answer:

x=30

y=17

Step-by-step explanation:

We know that 6x+9 = 129  since they are vertical angles

6x+9 = 129

Subtract 9 from each side

6x+9 -9 =129-9

6x = 120

Divide by 6

6x/6 =120/6

x = 20

3y+129 =180  since they make a straight line and straight line are equal to 180 degrees

3y+129 =180

Subtract 129 from each side

3y+129-129=180-129

3y = 51

Divide by 3

3y/3 = 51/3

y = 17
