Question

please solve question 3​

Answer 1

Answer:

A-B = π/4 or 45°

Step-by-step explanation:

Tan(A-B) = (Tan A - Tan B )/ 1 + Tan A Tan B

Tan(A-B) = (m/m-1 - 1/2m-1) / 1 + m /(m-1)(2m-1)

After cross multiplying and simplifying we get

Tan(A-B) = (2m2 -2m+1 ) / (2m2-2m+1 )

Tan(A-B) = 1

A -B = 45°
