Question

If sin A= 1/2 and cos B=1/2, then A+B=?​

Answer 1

Step-by-step explanation:

Solution: sin A = 1/2 or A = 30º

cos A = 1/2 or A = 60º

Hence A+B = 30+60 = 90º. D is the correct answer.

Answer 2

Answer:

sin30 degrees value is 1÷2 and cash 60 degrees value is 1÷2

Step-by-step explanation:

so,

30 degrees +60 degrees=90 degrees

so 90 degrees is answer
