Answer:

C = 25.12 , A = 50.24

In the triangle below, 4/5 represents which ratio?
ASHA 777 [7]
<span><u><em>Answer:</em></u>
sin (C)

<u><em>Explanation:</em></u>
<u>In a right-angled triangle, special trig functions can be applied. These functions are as follows:</u>
sin (theta) = </span>\frac{opposite}{hypotenuse}
<span>
cos (theta) = </span>\frac{adjacent}{hypotenuse}
<span>
tan (theta) = </span>\frac{opposite}{adjacent}<span>

<u>Now, let's check the triangle we have:</u>
<u>We have two options:</u>
<u>First option:</u>
5 is the hypotenuse of the triangle
4 is the side adjacent to angle B
Therefore, we can apply the <u>cos function</u>:
cos (B) = </span>\frac{4}{5}<span>

<u>Second option:</u>
5 is the hypotenuse of the triangle
4 is the side opposite to angle C
Therefore, we can apply the <u>sin function</u>:
sin (C) = </span>\frac{4}{5}
<span>
Among the two options, the second one is the one found in the choices. Therefore, it will be the correct one.

Hope this helps :)
