Suppose sin(a)=-0.78 use the trig identity sin^2(a)+cos^2(a)=1 and the trig identity tan(a)=sin(a)/cos(a) to find tan (a) in quad IV. Round to the nearest hundredth.

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
