Find the hypotenuse AB of right triangle ABC if BC is 12 and angle B is 60 degrees.
| December 2, 2020 | education
angle A = 180-90-60 = 30 ° (since the sum of the angles in any triangle is 180 °), therefore, AB = CB * 2 = 12 * 2 = 24 (in a right-angled triangle opposite an angle of 30 ° there is a leg, equal to half the hypotenuse)
Answer: 24.
