In a right-angled triangle, the angle C = 60 °, so the angle B = 90 °.
Find corner A.
180 – (90 + 60) = 30, angle A = 30 °
In a right-angled triangle, the leg opposite an angle of 30 ° is equal to half the hypotenuse. Since BC = 5, and this is a leg. Hence the hypotenuse AC = 5 * 2 = 10.
Answer: AC = 10.
