Question

trigonometry chapter class 10​

Answer 1

Answer:

Pls find the attached document below

Answer 2

tan(a+b)=1

tan(a+b)=tan45° [tan45=1]

using tan inverse to both side

a+b=45° --------(1)

tan(a-b)=1/√3

tan(a-b)=tan30°. [tan30=1/√3]

using tan inverse to both side

a-b=30. ---------(2)

adding 1 and 2

2a=75

a=37.5

b=2.5




hope this will help u!!!❤
