Question

In triangle ABC angle C is equal to 90 degree find Sin ( A+B)​

Answer 1

$\huge\boxed{Answer}$

Given, in Triangle ABC,

1) Angle C = 90 degrees.

2) Also in a triangle, A+B+C = 180 degrees.

3) A+B = 180-90 degrees = 90 degrees.

Answer 2

Step-by-step explanation:

as angle c = 90 deg ,

angle a+b+c=180deg

a+b=90 deg

sin (a+b)=sin 90=1
