Right triangles are triangles with a measure of 90 degrees
The relationship between the ratios of sin x and cos y is that both ratios are equal
<h3>How to determine the relationship</h3>
From the triangle, the sine and the cosine ratio are:
By comparing the above ratios, we have:
Hence, the relationship between the ratios of sin x and cos y is that both ratios are equal

B is correct
Explanation is that you add 2 to both sides and this you divide that by 3 and you get -3
5/8x + 1/5x can be written with a common denominator:
25/40x+ 8/40x = 99
This can be simplified to:
33/40x = 99
Next times both sides by 40
33x = 3960
Then, divide both sides by 33
x = 3960/33
x = 120
Answer:
y = -4
Step-by-step explanation:
This is because any point on that line would have a y coordinate of -4 → e.g. (6, -4), (-2, -4), and it intercepts the y axis at -4.
Hope this helps!
