Answer:
The answer to your question is:
Step-by-step explanation:
1.-
y = 84°
5x - 61 = 84
5x = 84 + 61
5x = 145
x = 29
2.-
m∠1 + m∠6 = 180 they are supplementary angles
∠1 = 180 - 143
∠1 = 37
∠1 = ∠ 3 because are vertical angles.
3.-
m∠2 + m∠5 = 180 they are supplementary angles
∠2 + 79 = 180
∠2 = 180 - 79
∠2 = 101
m∠3 = m∠5 they are alternate angles
Answer: The value necessary from the set to make the equation true was 11.
Step-by-step explanation:
Process of elimination:
1. 2([10]-5)
= 2(5)
= 10, not 12.
2. 2([11]-5)
= 2(6)
= 12; the answer we need.
We substituted x for 11, and then the equation worked; so therefore the value we needed from the set was 11.
