RIGHT TRIANGLE STUFF

In each of the following, c is the hypotenuse, g the right angle, a the leg opposite angle a , and b the leg opposite angle b .

1. a = 45 , c = 4

2. b = 60 , a = 3

3. a = 5, b = 6  

4. a = x, b = 1
 
5. a = 2, c =

6. c = x, a = 1   

7. b = y, c = 2

8. a = 30 , a = x
Find a, b, tan b

Find b, c, sin b , sec a

Find c, sin a , tan b

Find c, sin a , tan b

Find b, cos a , tan a

Find b, sin a , sin b , tan b

Find a, sin a , cos a , tan b

Find b, c, tan b

3.     c =
        sin a =
        tan b = 6/5
4.    c =
        sin a =
        tan b = 1/x
5.      b =
       cos a =
        tan a =
6.     b =
        sin a = 1/x
      sin b =
        tan b =
7.     a =
        sin a =
        cos a = y/2
        tan b =
8.     b =
