Question

Sin 690 degree + tan (-765 degree)

Answer 1

Answer:

-1. 5

Step-by-step explanation:

sin 690° = -0.5

tan (-765°) = -1

so, -0.5+(-1) = -1.5

Answer 2

Answer:

Sin 690°=Sin(690-360)

=Sin(330)=Sin(-30)=1/2

Step-by-step explanation:

and tan(-765°)

=tan(-765+720)

=tan(-45°)

=1

So sin(690°)+tan(-765°)

=(1/2)+1

=3/2

or 1.5 ANS
