Question

Enter the trigonometric equation you would use to solve for x in the following right triangle. do not solve the equation.

Answer 1

For this case what you should do is use the following trigonometric relationship:

sine (theta) = C.O / h

Where,

theta: angle

C.O: opposite leg

h: hypotenuse

Substituting values we have:

Answer:

sine (80) = 9 / x
