Question

Given that sina =V3/2 and cosB = 0, then the value of B-a is

a) o
b) 90
c) 60
d) 30​

Answer 1

Answer:

Sin=root3/2=60 and cosb=0=90

B=90 and a=60

A-b=90-60=30 so correct

answer is d=30

Answer 2

Answer:

Hey guys hope this answer would be helpful for you

Step-by-step explanation:

sin a =V3/2

sin 60 degree = V3/2

a = 60

cos B = 0

cos 90 degree = 0

B-a =

90-60

which is equals to (d) 30
