Trig- Determining which function to use

You want to find a missing side length, you would use...

• trig

  sinx, cosx, or tanx

You want to find a missing angle measure, you would use...

• trig

  sinx, cosx, or tanx

This problem is asking us to solve for a missing ​ (a)   and we should use ​ (b)   trigonometry to solve for it.

• angle
• side
• inverse
• regular

Determine which trig function should be used to find the missing measurement.

Beware: There are not 3 triangles in each category

Groups:

(a) Sin or Inverse Sin

,

(b) Cos or Inverse Cos

,

(c) Tan or Inverse Tan
