PZ HURRY. find angle b.

b = 60°

Step-by-step explanation:

If you look at the side under the 30° angle, there's a small red box, signifying a right (90°) angle. Doing the math, then, you would do:

90 = 30 + b

b = 60

c

step-by-step explanation:

at least i think its

(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
