Answer:
134°
Step-by-step explanation:
Supplementary angles when combined = 180°
One of the angles is x°. The other is x + 88°. Set the equation:
x + x + 88 = 180
Simplify. Combine like terms:
(x + x) + 88 = 180
2x + 88 = 180
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
Subtract 88 from both sides:
2x + 88 (-88) = 180 (-88)
2x = 180 - 88
2x = 92
Divide 2 from both sides:
(2x)/2 = (92)/2
x = 92/2
x = 46
The supplement angle is 46° long.
Find the angle you are solving for: 88 + 46 = 134°
134° is your answer.
The supplement angle is 46°.
