Question

If∆ABC is right angled at C the find the value of Sin(A+B)

Answer 1

Answer:

if the ∆ABC is right angle at C

so we say the ans is 1

Step-by-step explanation:

let me explain you.

The sum of angle of triangle is nothing but 180°

So if it is right and at C

so C=90°

From this we get that A+B

will be equal to 90°

so sin(A+B)=sin90°=1

hence proved....
