1.)subtract 600 from 750 in order to simplify
2.)divide by 15 on both sides to get y alone. Doing this cancels the 15 on the y and makes the right side equal 10
3.)y=10
Answer:
it's 4488 Wich would make 187
We can seperate (3b³) into two different parts, the constant and the variable.
The constant (3) and the variable (b) can both be squared and multiplied to get the correct answer, so:
3² = 9
(b³)² = 
So, 
90° - 59° = 31°
31° is your answer
I don't mean to sound rude or anything but if you go off of the directions up top then you might be able to find the answer these questions are fairly easy and understandable
