Solve for x , look at image above

x=16

Step-by-step explanation:

This problem can be solved by using proportions. We can see the figure as 2 triangles. One is ΔAED and another is ΔACB.

                         [cross multiply]

               [distribute]

                [subtract both sides by 8x]

                          [divide both sides by 3]

We know that x=16.

he answer is x=1x3 because x=1 to x=3

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q
