-A)=0, then Sin (A+B)=​

Answer 1

hope it helps..

Answer 2

Answer:

(We know that There are three angles in a triangle so the 90 degree angle will be C so other two will be A and B whose sum is (180°-angle C)

so A+B=90°)

Step-by-step explanation:

cos(90-A)=0

but cos 90°=0

so angle A we can say is 0

so angle will be equal to 90°-A

=90-0=90

so sin (A+B)= sin 90° =1
