Answer:

1. tan

2. standard

3. y=16.8

Step-by-step explanation:

1. Trigonometic functions are:

sinA=opposite/hypoteneuse

cosA=adjacent/hypoteneuse

tanA=opposite/adjacent.

We have the opposite side (20) and the adjacent side (y), but not the hypoteneuse, ao we have to use tan.

2.Inverse is only used when we dont know the angle measure, so we use standard.

3.tanA=opp/adj

tan50=20/y

1.19175359259=20/y

y=16.7819926235 or 16.8

Which set of steps shows the solution to the equation 4y = −12? (5 points)
PilotLPTM [1.2K]

To find the solution, you want to isolate y. This is a one-step problem, as all you need to do is divide both sides of the equation by 4.

4y = -12

4y/4 = -12/4

y = -3

Answer:

-3
