(A) because a right angle is 90 degrees and has a equal eqivalent to get to 100
Lana71 [14]3 years ago

Answer:

Option A is true

Step-by-step explanation:

Consider a right triangle ABC right angled at B.

Then we have A+C=90 since sum of all 3 angles =180

A and C are complementary

A has opposite side as BC and hypotenuse as AB

sin A = BC/AB

Consider angle B.

B has adjacent side as BC and hypotenuse as AB

So cos B = BC/AB

i.e. sin A = cos B

Hence we have option A to be true.
