Question

trigonometry please solve this mam/sir​

Answer 1

Answer:

a = 37.5°

b = 7.5°

Step-by-step explanation:

Tan (a+b) = 1    hence a+b = 45°---(1)

Tan (a-b) = 1/√3   hence a-b  30°---(2)

Equate Eqn (1) & (2)

a+b = 45---(1)

a-b = 30---(2)

2b = 15

b = 7.5°

Put b in (1) or (2)

We get a =

a = 30 + 7.5

a = 37.5°

Trigonometric values

Tan 30° = 1/√3

Tan 45° = 1

Tan 60° = √3

Tan 90° undefined
