Answer:
x = <u><em>8</em></u>
The missing measures are <em><u>85</u></em> degrees
Step-by-step explanation:
Since 9x + 13 and 11x - 3 are on opposite sides, they are equal, so
9x + 13 = 11x - 3
Subtract 13 from both sides:
9x = 11x - 16
Subtract 11x from both sides:
-2x = -16
Divide both sides by -2:
x = 8
The angle measures are
9(8) + 13 = 72 + 13 = 85
11(8) - 3 = 88 - 3 = 85
Answer:
9x+13 = 11x-3
x = 8
The angles are 85
Step-by-step explanation:
The angles are vertical angles so they are equal
9x+13 = 11x-3
Subtract 9x from each side
9x+13 -9x = 11x-9x-3
13 = 2x-3
Add 3 to each side
13+3 = 2x-3+3
16 =2x
Divide by 2
16/2 = 2x/2
8 =x
11x-3 = 11(8) -3 = 88-3 = 85
