Angle α and β are supplementary angles and when added together equal 180.
Set up an equation:
α + β = 180
β = α +30
Replace β in the first equation, to get:
α + α +30 = 180
Simplify:
2α +30 = 180
Subtract 30 from both sides:
2α = 150
Divide both sides by 2:
α = 150 /2
α = 75 degrees.

The answer is 3. Hope this helped! Good luck! Let me know if you have any more questions! :)
I would say C is the answer
Answer: 7^17
Step-by-step explanation:
(7^5 * 7^3)^4 = 7^32
7^32 * 7^-2 = 7^30
7^-7 * 7^20 = 7^13
7^30 / 7^13 = 7^17
