When (5x-6)(3x^2 - 4x - 3) is multiplied, how many terms are there before combining like terms?

In the diagram, the measure of angle 9 is 85° which angle must also measure 85°?

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

Write the expression as a constant , a single trigonometric function, or a power of a trigonometric function. sin x cos x/ tan x
