If 5sinθ = 4, then the value of (secθ + 4cotθ)/(4tanθ - 5cosθ) is:
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e 2
| Understanding | Application |
| We will use the basic principles of trigonometry to put the values in the given sum. |
Given that, 5sinθ = 4 ⇒ Sinθ = 4 / 5
By the given diagram we could put values in the sum as ⇒ (5 / 3 + 4 × (3 / 4))/(4 × (4 / 3) - 5 × (3 / 5)) ⇒ (14 / 3) / (7 / 3) ⇒ 2 |
