`(1)/(sin theta)+(1)/(cos theta)=`

A

`0.75`

B

`1.20`

C

`1.43`

D

`2.92`

Text Solution

Verified by Experts

The correct Answer is:
D
Since is opposite over hypotenuse and cosine is adjacent over hypotenuse, so `sin theta = (4)/(5)` and `cos theta = (3)/(5)`. Therefore,
`(1)/(sin theta)+(1)/(cos theta)=(5)/(4)+(5)/(3)~~1.25+1.67=2.92`
