If cotB = 158\frac{15}{8} where B is an acute angle, what is the value of sec B + tan B?

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. 53\frac{5}{3}

Given that

 If cos B = 158\frac{15}{8} = B/P

According to the question

Hypotenuse = √(152 + 82) = √(225 + 64) = √289 = 17 

the value of sec B + tan B

⇒ sec B + tan B

⇒ H/B + P/B

⇒ 17/15 + 8/15

⇒ 25/15 = 5/3
