Questions
In a triangle ABC, angle A is greater than B, if the measures of angle A and B satisfy the equation
Then the measure of angle C is
detailed solution
Correct option is C
Given A>B and, A and B satisfy the equation 3sinx−4sin3x−k=0⇒sin3x-k=0 (or) sin3A−k=0 and sin3B−K=0 ∴sin3A=sin3B=sinπ-3B ⇒ 3A=π−3B ∵A>B⇒ A+B=π3 Then C=π−π3=2π3Talk to our academic expert!
