SSC CGL 2019 PYQ — Question 56

SSC CGL - 4th June 2019 - Shift 3 • Quantitative Aptitude • Q56

The value of θ, when √3cos θ + sin θ = 1 (0° ≤ θ ≤ 90°), is?

Show answer & explanation

Correct answer: A

Explanation

Correct Answer is option 1 i.e. 90°

Understanding

Application

Given 

√3cosθ + sinθ = 1

(0° ≤ θ ≤ 90°)

√3cosθ + sinθ = 1

Checking all the options:

Put θ = 90°

⇒ √3cos90 + sin90

⇒ √3 × 0 + 1

⇒ 1

Hence, option 1 is correct.
