Question

If x and y lie in first quadrant, sinx + cosy = 2, what is the value of x + y ?​

Answer 1

Answer:

90

Step-by-step explanation:

For sin x + cos y to be equal to 2, values of sin x and cos y should be maximum i. e. 1 each

Sin 90 degrees = 1

Cos 0 degree=1

Therefore x= 90 and y= 0

Hence x+y= 90+0= 90
