Question

State whether each sentence is true or false. If false, replace the underlined word, phrase, expression, or number to make a true sentence.

The cosine of an angle is found by dividing the measure of the side opposite the angle by the hypotenuse.

Step-by-Step Solution

Answer

The given sentence is False.

The true sentence is The cosine of an angle is found by dividing the measure of the side adjacent the angle by the hypotenuse.

Step 1. Determine whether the given sentence is true or false.

The given sentence is false because the sine of an angle is found by dividing the measure of the side opposite the angle by the hypotenuse and the cosine of an angle is found by dividing the measure of the side adjacent the angle by the hypotenuse.

Step 2. Write the true sentence.

Therefore, the true sentence is the cosine of an angle is found by dividing the measure of the side adjacent the angle by the hypotenuse.
