Wayne's garden is triangle-shaped with two equal sides and a third side that is 4 ft more than the length of an equal side. if the perimeter is 49 ft, how long is each side? which equation represents this? 2x = 49 2x + 4 = 49 3x = 49 3x + 4 = 49

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

Abby is preparing fruit punch for her party. she starts with a bowl filled with liquid that has 1/2 fruit juice and 1/2 sprite, but she decides it's too fruity. so she pours out 1/4 of the liquid, and then fills the bowl up again with sprite. what fraction of the punch is now sprite?
