Please help me solvung the above question....​

Answer 1

Answer:

so here is the answer my friend

Answer 2

Answer:

A=45°

B=15°

Step-by-step explanation:

sin(A-B)=1/2

sin(A-B)=sin30°

A-B=30°.....(1)

cos(A+B)=1/2

cos(A+B)=cos60°

A+B=60°.....(2)

By solving equation (1)and(2)

A-B=30°

A+B=60°

________

2A =90°

A =90°/2

A =45°

A=45°

Substitute 'A' value in equation no (2)

A+B=60°

45°+B=60°

B=60°-45°

B=15°

B=15°.
