D) Vertices: (1, -1), (-11, -1); Foci: (-15, -1), (5, -1)
1/2=4/8. 3 and 4/8+ 3 and 3/8 is 6 and 7/8.
Step-by-step explanation:






Answer:
Step-by-step explanation:
Tan(51) = opposite / adjacent
The adjacent side makes up the reference angle (51o)
The opposite side is not part of the reference angle
adjacent side = x
opposite side = 16
Tan(51) = 16 / x Multiply both sides by x
x * Tan(51) = 16 Divide by tan 51
x = 16 / tan(51)
tan(51) = 1.2349
x = 16 / 1.2349
x = 12.96
