Answer:

D) Cos X = Sin Y

Step-by-step explanation:

If angle X and Y are complementary angles, as shown in the attachment, then;

\cos X=\frac{a}{b}

and

\sin Y=\frac{a}{b}

We can see clearly that both ratios are the same.

This implies that:

\cos X=\sin Y

Therefore the correct answer from the given options is D

Which fraction equals the ratio of rise to run between the points (0, 0) and (6, 7)? A. B. C. D.
Svetlanka [38]

Answer:

7 / 6

Step-by-step explanation:

Given the points:

points (0, 0) and (6, 7)

Point 1 : x1 = 0 ; y1 = 0

Point 2 : x2 = 6 ; y2 = 7

The rise = y2 - y1 = 7 - 0 = 7

The run = x2 - x1 = 6 - 0 = 6

Ratio of Rise to Run = Rise / Run = 7 / 6

zepelin [54]

Answer:

<h2>y = 54 ✅</h2>

Step-by-step explanation:

If the two numbers vary directly, we can use a proportion to find the missing value.

36/4 = y/6

4y = 216

Divide by 4

y = 54

Check

36/4 = 54/6

216 = 216 ✅
