Find the value of x. round to the nearest tenth. (will give brainliest)

x = 51.1 degrees

Step-by-step explanation:

As this is a right triangle, we may use Sin, Cos, and Tan in order to find this answer. Sin is defined as the opposite over the hypotenuse, so that is what we can use. 7 is the opposite value and 9 is the hypotenuse of the triangle.

So we can set up an equation like this

Then we can use the inverse of sin in order to solve for x

When this is plugged into a calculator you get:

degrees

This rounds to 51.1 degrees

0.5 meters per second
