Question

A right triangle has a hypotenuse of length 24 and an angle of 30°, with a side opposite this angle of length 12. A second right triangle also has an angle of 30°, with a hypotenuse of length 12. Determine the length of the side opposite the 30° angle on the second triangle. (1 point)

Answer 1

The side opposite the 30° angle is half the hypotenuse. For hypotenuse 12 that side = 12/2 = 6.
