Answer:
None of them
Step-by-step explanation:
-16 y+13
16(−y+2) = -16 +32
−16(−y+13)
= 16y -208
−16(y+2) = -16y -32
16(−y+13)= -16y+208
Answer:
? = 47°
Step-by-step explanation:
The angle marked B at the intersection of the secants is half the difference of the arcs they intercept.
∠B = (DE -AC)/2 = (142° -48°)/2 = 47°
The unknown angle is 47°.

This is actually a lot easier than it seems :-)! There is a formula in trig called the Pythagorean Theorem. This is cos^2 x + sin^2 x = 1. This means that cos^2 x means the exact same thing as 1-sin^2 x. If we plug this in, we get 1-2sin^2 pi/9. Another helpful trigonometric equation is the double angle identity. This is cos(2x)=1-2sin^2 (x). Plugging our equation from earlier in, we get cos 2pi/9.
