answer: we can see that

$\sin x\textdegree=\cos y\textdegree$

step-by-step explanation:

since we have given that

in triangle abc, ∠b=90°

as shown in the figure, ab = 24

ac = 25

bc = 7

so, we use the "trigonometric ratios":

$\sin x=\frac{perpendicular}{hypotenuse}\\\\\sin x=\frac{24}{25}$

here, perpendicular is the leg opposite to angle x.

similarly,

$\cos y=\frac{base}{hypotenuse}\\\\\cos y=\frac{24}{25}$

hence, we can see that

$\sin x\textdegree=\cos y\textdegree$
