How do you do this, I keep on getting 3..

There is a right triangle. One angle is 30 degrees. The hypotenuse is 24. What is the value of x, the adjacent, to the
nearest whole number?

a. 12
b. 14
c. 21
d. 28

  • Math - ,

    There is one side that must be half as long as the hypotenuse. The length of that side is 12. That is the side opposite the 30 degree angle. The other side has a length of
    sqrt[(24)^2 - (12)^2] = 20.78
    The nearest whole number is 21.

    You have not indicated which side is x.
