Answer:

x = 10.6, y = 39.6

Step-by-step explanation:

Given that,

Angle A = 75°

Angle B = 90°

Angle C = 180-(A+B)

= 15°

Now, using trigonometry,

[tex]\sin C=\dfrac{x}{41}\\\\x=41\times \sin C\\\\=41\times \sin(15)\\\\x=10.6[/tex]

For y, using Pythagoras theorem,

[tex]y=\sqrt{41^2-10.6^2} \\\\y=39.6[/tex]

Hence, the value of x is equal to 10.6 and that of y is equal to 39.6.
