Answer:
160°
Step-by-step explanation:
Take notice that m∠1 and m∠2 are supplementary angles, meaning their angle measures will add up to 180°.
Since we know m∠2, we can find m∠1 easily.
180-20=160°
Hope this helped!
Y= 7x - 7z -9
+9 +9 Y+9+7z /7=x
Y+9 = 7x - 7z
+7z +7z
Y+9+7z = 7x
/7 /7
Answer: y=-4x+7
Step-by-step explanation: Move 8x to the right side to isolate y. 2y=14-8x. Divide the whole equation by 2 to get y by itself. y=7-4x
I think C.12
5*12 is 60
60+80 is 140
And I think it’s a 140 degrees
