Which of the following values best approximates the length of c in triangle abc where c = 90 degrees, b = 12, b = 15 degrees

We apply the Law of Sines 

a/sin A = b/sin B = c/sin C

We have that b = 12, B = 15 degrees

C = 90 degrees

....> c/sin(90) = 12/sin(15)..............> c = 12/0.258 = 46.3644 

the first one

step-by-step explanation:

just id the test.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
