Question

If triangle ABC right angled at B what is the value of Sin(A+C)?

Answer 1

let us consider a triangle ABC, having angles a, b, and c...
by angle sum prop we know
$a + b + c = 180 \\ a + 90 + c = 180 \\ a + c = 90$
so,
$\sin(a + c) = \sin(90) = 1$

Answer 2

Answer:

Sin (A+ C ) = 1

Step-by-step explanation:

Triangle ABC is right angled meaning, the angle B is 90°. A triangle has a total of 180° . This means that the angles A and C will add up to 90°.

Therefore, Sin (A+C) = Sin 90°

Sin 90° = 1

Hence, Sin (A + C) = 1
