Which equation can be used to solve for in the following diagram? Choose 1 answer
A: (X+45) = 90 - 60
B:60+ (X+45) = 180
C:60+ (X+45) = 90
D:60 = (X+45)

(i’ll first response give you brainiest)

4+6x-3x^3 in standard form with explanations because i don’t understand

Which sum or difference identity would you use to verify that cos (180° - ∅) = -cos ∅? a. sin (α -β) = sin α cos β – cos α sin β b. cos (α -β) = cos α cos β – sin α sin β c. cos (α -β) = cos α cos β + sin α sin β d. sin (α + β) = sin α cos β + cos α sin β

If f(x) = x+8 and g(x) = 4x- 3, find (f+g)(x)
