Question

Can you please help me

Answer 1

Take into account the length of the right side of the figure is 10. Moreover, x is the hypotenuse of a right triangle. To find the value of x, use the sine function:

cos 45 = opposite side/hypotenuse

cos 45 = 10/x solve for x

x = 10/cos 45

x = 10/0.707

x = 14.14

with the previous value of x, you can find y. Again, consider the right triangle right side. x is the hypotenuse. Use the Pythagorean theorem to find y:

x² = 10² + y² solve for y and replace x

y² = x² - 10²

y² = (14.14)² - 100

y² = 200 - 100

y² = 100 apply square root both sides

y = 10

Hence, the values of x and y are 14.14 and 10 respectively
