Find the measure of the numbered angle.
m∠8 =
2 answers:
Answer:
∠ 8 = 140°
Step-by-step explanation:
∠ 8 and 40° are adjacent angles and supplementary ( sum to 180° ), then
∠ 8 = 180° - 40° = 140°
Answer:
m∠8 = 140°
Step-by-step explanation:
40 and angle 8 are supplementary angles
this means they add up to 180°
so, you can make the following equation:
40 + m∠8 = 180
<em>subtract 40 from both sides of the equation</em>
40 - 40 m∠8 = 180 - 40
m∠8 = 180 - 40
m∠8 = 140
