30 points If the sin 90° = 1, then which statement is true?

Question 8 options:

cos 0° = 1, because the angles are complements

cos 90° = 1, because the angles are supplements

cos 0° = 0, because the angles are complements

cos 90° = 0, because the angles are supplements

In given triangle sin 90° = 1

and we know the relation between cosine and sin is represented by

Therefore,

➪Therefore, cos 0° = 1 will be the answer...~

We know

Option A

i think the answer is seven, for if i'm being useless °ω°

step-by-step explanation:

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
