Question

The hypotenuse and one of the legs of a right triangle form an angle that has a cosine of square root 2 over 2 . What is the measure of the angle? PLZZZZZ HELP

Answer 1

To answer this question, you can use the values of the unit circle to figure out the angle measurement. Since the cosine is the x value of the circle, we can see that at 45°, the x value is √2/2.
So the missing angle should be 45°
