Missing Angle

1. Draw and label the triangle
2. I had the opposite and hypotenuse side measurements so I used Sin.
3. I wrote my equation (sinX = 12/40)
4. then I put it into my calculator and used sin- to solve my equation

 

Missing Side1

1. Draw and label triangle
2. I had the opposite side measure to and the angle to find the ajocent side so I used tan
3. I wrote my equation (tan25 = 15/x)
4. then I out it into my calculator and solved it

 

Missing Said2

1. draw and label triangle
2. I had the hypotonuse measurement and the angle to find the adjacent side so I used cos
3. I wrote my equation (cos5 = x/10
4. because x was over ten I divided and used my calculator to solve the problem
