Question

In a right angled triangle, if angle A is acute and cot A = 4/3. Find the value of cosec A.

Answer 1

Step-by-step explanation:

as we know trigonometric identitity 1+(cot^2)A=(cosec^2)A

cotA=4/3

So, apply 1+(4/3)^2=(cosec^2)A

1+16/9=(cosec^2)A

25/9=(Cosec^2)A

Cosec A=√(25÷9)

Cosec A=5/3

answer is 5/3
