Sin A + cos B = 1 ,A = 30 and B is an acute angle then find the value of B

B=60°

Step-by-step explanation:

So sin(30)+cos(B)=1

1/2+Cos(B)=1

Cos(B)=1-1/2

Cos(B)=1/2

So

B=acos(1/2)

B=60

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.
