Calculate the size of unknown angles​

I'll just take it as you're trying to find y

Step-by-step explanation:

y + 2y =150

3y =150

y = 50

Hi! I'm happy to help!

We know that 2y=150, so we can divide both sides by 2 to find the angle of y

2y=150°

÷2  ÷2

y=75°

So, y=75°.

I hope this was helpful, keep learning! :D

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
