Question

Sin (a+b)=1 cos(a-b)=1/2 find a and b

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:sin(a+b)=1

Sin(a+b)=sin 90

a+b = 90

a = 90- b ------------1

Again

Cos(a-b)=1/2

Cos(a-b)=cos60

a-b =. 60

a. = 60+b---------2

From 1 and 2 we get

90-b=60+b

2b. =30

b. =15

There fore

a=60+b

=75
