Two sides of a parallelogram meet at an angle of 42 degrees. If the length of one side is 10 inches and the other side is 14 inches, what is the length of the shortest diagonal of the parallelogram?

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 the scale factor between two circles is 2x/5y what is the ratio of their areas?

Written as a simplified polynomial in standard form, what is the result when (2x+8)^2(2x+8) 2 is subtracted from 8x^2-38x 2 −3?
