Question

If cosec 0+ cot O = 5 then evaluate Sec O​

Answer 1

Answer:

cosec 0+ cot 0=5

1/sin 0 + cos 0/ sin 0=5

1+cos 0/ sin 0=5

1+ cos 0 =5sin0

cos 0=5 sin0/1

sec 0=1/ 5 sin 0

Step-by-step explanation:

hope it help you

Answer 2

Step-by-step explanation:

cosecθ+cotθ=5

➡(1+cosθ)/sinθ=5

➡1+cosθ=5sinθ

➡(1+cosθ)²=25sin²θ

➡(1+cosθ)²=25(1-cos²θ)

➡(1+cosθ)²=25(1+cosθ)(1-cosθ)

➡1+cosθ=25(1-cosθ)

➡1+cosθ=25-25cosθ

➡26cosθ=24

➡cosθ=24/26=12/13

➡secθ=13/12
