Question

if cos(A+B) = 0 and cot(A-B) = √3, then find the value of A and B?
pls. tell its urgent ​

Answer 1

Answer:

A=60°, B=30°

Step-by-step explanation:

cos(A + B) = 0

or, A + B = cos⁻¹0

A + B = 90°

cot(A - B) = √3

or, A - B = cot⁻¹√3

A - B = 30°

Combining both,

A + B + A - B = 90° + 30°

or, 2A = 120°

A = 60°

B= 90° - A = 90°- 60° = 30°
