Question

In triangle A B C, angle C is a right angle and BC = 11. If lower m angle B equals 30 degrees, find AC.

Answer 1

Since angle C is a right angle, triangle ABC is a right triangle.

Using trigonometry, we can find AC:
sin(30 degrees) = AC/11
AC = 11 * sin(30 degrees)
AC = 11 * 0.5
AC = 5.5

Therefore, AC is 5.5 units long.
