Find the value of x. Your answer must be
Exact

Step-by-step explanation:

Use the sine ratio because we have the hypotenuse and side opposite the given angle to work with:

Insert the values:

Multiply both sides by x:

Divide both sides by sin30°:

Insert the value of x into a calculator:

OR:

The little red square means that angle is 90º, and the other given angle is 30°. Since every triangle has a measure of 180°, the other missing angle is 60°. The given triangle is a 30°-60°-90° triangle with the following rules:

The hypotenuse is represented by the variable x. We are given the value of the short leg, which is 4. Solve for the hypotenuse:

Therefore, the value of x is 8.
