Question

What trig function am I looking for here? Sin, Cos, or Tan? (See Attachment)

Answer 1

Depends on which of the missing sides you want to find.

Answer 2

It simple says solve the triangle. The previous questions I solved all the missing angles and sides.

Answer 3

Alrighty. So in regards to the angle, do you know which side the 22.6 is?

Answer 4

The hypotenuse is always straight across from the right angle, so its not the hypotenuse.

Answer 5

Oh that would be the opposite, my mistake.

Answer 6

Right. So now we need to use a trig function that includes the opposite side. That means we cannot use cosine because cosine is adjacent/hypotenuse. So for now, you can choose sin or tangent to get us one of the missing angles.

Answer 7

Lets use sin. so o/h

Answer 8

Right. So we would have sin62 = 22.6/x where x is the missing side of the hypotenuse. You okay solving for that?

Answer 9

sin62= 22.6/62 (skipping the work)

Answer 10

x= 22.6/62 is the setup correct?

Answer 11

divided by sin62, not just 62.

Answer 12

Yes sin62. I'm good now, thank you!

Answer 13

Alright, cool xD
