Question

in triangle abc angel A =90 find the sin of B+C​

Answer 1

The sum of area in a triangle is 180°

Given that angle C is 90°

So, angle A+B = 180° - 90° = 90°

Sin(A+B) = Sin(90°) = 1 (ANSWER)

Please mark me as brainliest !!!

Answer 2

Answer:

A +B+C = 180*

90 + B+C= 180*

B+C= 180-90

B+C= 90

sin( B+C) = sin(90)

=1

I hope it may help you
