Question

If Δ ABC is right angled at B, what is the value of sin (A + C).

Answer 1

Answer:

1

Step-by-step explanation:

A+ B + C = 180° ( angle sum property of a triangle)

A+ 90 + C = 180

A+ C = 90

sin ( A+B) = sin 90 = 1

Answer 2

Answer:

1

step-by-step:

A+B+C=180°(angle sum porperty of a triangle)

A+90+C=180

A+C=90

sin(A+B)=sin90=1
