Question

Use a trigonometric ratio to find the value of x. Round your answer to the nearest
tenth.

Answer 1

x = 7.6

Explanation:

Label the values you have on the triangle: The X is opposite, the 33 is your theta (ø) and 14 is your hypotenuse

Plug these values into the equation sin(ø)=o/h making the equation sin(33)=x/14.

Take the 14 and multiply it on the opposite side, making the equation look like this: 14xsin(33)=x

Then plug this into the TI-83/84 calculator and make sure it is degree mode (mode, degree)

Then just round to the nearest tenth. :)
