Question

In the given figure, ABC in a right-angled triangle, right-angled at B. If BC = 5 cm and AC -AB = 1 cm, find the value of cOsec A and cos A. ​

Answer 1

Answer:

ab- ac = 5 common is bc so that answer is 5

Answer 2

Step-by-step explanation:

Let AB = p

AC = 1+p

AC² = AB² + BC²

or, (1+p)² = p² + 5²

or, p= 12

Cosec A = 13/5

Cos A = 12/13
