Question

if cos A=1/2 and sin B=1/2, find the value of tanA-tanB/1+tanA tanB. Here angle A and angle B are different right triangles.​

Answer 1

Answer:your answer is 1/√3.

Step-by-step explanation:

Given

cos A=1/2

A=60°

Sin B=1/2

B=30°

Given,

=tanA-tanB/1+tanAtanB

=tan(A-B)

=tan(60°-30°)

=tan(30°)

=1/√3
