Question

if sin (A-B)=1/2, cos(A+B)=1/2 where A+B is lesser than 90°A is greater than B find A and B​

Answer 1

Answer:

A=45,B=15

Step-by-step explanation:

sin 30°=1/2

cos 60°=1/2

so,A-B=30

A+B=60

using elimination method

2A=90

A=45

A+B=60

45+B=60

B=15

Answer 2

Answer:

A = 45.                                                       B = 15
