if the sin 0° = 0, then which statement is true? (6 points)
o
cos 90º = 1, because the cosine and sine are complements
cos 180°
1, because the cosine and sine are supplements
cos 90º = 0, because the cosine and sine are complements
o
cos 180º = 0, because the cosine and sine are supplements

, because the cosine and sine are complements

Step-by-step explanation:

Sine and cosine are trigonometric complementary functions. If we are talking about a right triangle we will have the following:

cos 90° = 0, because the angles are complements

Step-by-step explanation:

cos 90° = 0

sin 0° = 0

sin and cos are complementary

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

35 is an outlier
