Answer 2

Answer:

ATQ

sin(a+b+c) = 1 .....(1) as sin90 = 1

tan(a-b) = 1/√3 ....(2) as tan30 = 1/√3

cos(a+c) = 1/2 ....(3) as cos60 = 1/2

from ...(1)

we get

a + b + c = 90 ....(4)

and

from ...(2)

a-b= 30 .....(5)

and from ..(3)

a+c = 60 ....(6)

by putting a+c = 60. in eqn ....(4)

we get

b= 30

now put this in eqn ...(5)

we get

a= 60

now put this in eqn ...(6)

we get

c = 0

so the value of c is 0
