In a right-angled triangle, one of the legs is 5 cm, and the tangent of the opposite angle to it is 1.25, find the second leg
| March 2, 2021 | education
1. Vertices of the triangle A, B, C. Tangent ∠A = 1.25. BC = 5 cm.
2. Calculate the length of the desired AC leg:
ВС / АС = tangent ∠А = 1.25.
AC = BC / 1.25 = 5 / 1.25 = 4 cm.
Answer: the length of the AC leg = 4 cm.
