Question

If (1+cosA) (1-CosA) = 3/4 , then What is
the value of secA? ​

Answer 1

Answer:

2

Step-by-step explanation:

given, (1+cosA) (1-CosA) = 3/4

=> 1² - cos²A = 3/4

=> 1-cos²A = 3/4

=> sin²A = 3/4

=> sinA = $\sqrt{ \frac{3}{4} }$ = $\frac{\sqrt{ 3} } {2}$

=> A = 60°

so, secA = sec60° = 2

Answer 2
