ABC triangle C = 90 (degree) A = 30 (degree) AB = 100cm, find the length of BC.
| June 2, 2021 | education
∠ С = 90 ° (according to the problem statement)
∠ А = 30 ° (according to the problem statement)
AB = 100cm (according to the condition of the problem)
Side BC lies opposite angle A. Opposite an angle of 30 ° lies a leg equal to half of the hypotenuse. Therefore, the BC side = 1 / 2AB.
Substituting numbers into the formula.
We get: BC = 100: 2 = 50
Answer: BC = 50cm
