If the cos 90° = 0, then the sin 0° = . (1 point) 0, because the angles are complementary 1 over 2 , because the angles are complementary square root 3 over 2 , because the angles are supplementary 1, because the angles are complementary

25% is the answer

answer: 0.26

i used the calculator on google

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
