The answer is 30. if 1 is 120 then that means 2 is 60 and vertical angles go to 90 so it would have to be 30 to get to 90. I hope this helped:)
Answer:
42.42641
Step-by-step explanation:
So in distributive property you multiply the outside number by the two inside so in this case 2(a) + 2(-2) = 3(a) + 3(-5)
Which will give you
2a+ - 4 = 3a + - 15
Or
2a-4=3a-15
Then if your solving for a your can subtract 3a from 2a giving you
- a-4=-15
Then add 4 to - 15
-a =-11
Then divide by negative 1 (this is so a isn't negative)
A=11
Hope this helps!
