Question

8. Given that sinA =
root3/2
and cosB = 0, then the value of A + B is (a)120 degree
(b) 60degree (c) 90degree (d) 150degree​

Answer 1

Answer:

sinA=√3/2

cosB=0

we know that,

sin60=√3/2

cos90=0

taking A=60 and B=90

A+B=90+60

=150°

Answer:

90 degree

Step-by-step explanation:

sin 60 =√3/2
