What are the values of x and y?

d1i1m1o1n [39]

Answer:

Step-by-step explanation:

y is the value obtained from 4 and 12

y^2 = 4 * 12 Combine

y^2 = 48 Square root both sides.

√y^2 = √48

y = √(3 * 4 * 4)

y = 4√3

Use the Pythagorean Theorem to obtain x

x^2 = y^2 + 4^2

x^2 = 48 + 16

x^2 = 64 Take the square root of both sides

√x^2 = √64

x = 8

Answer

x = 8
y = 4√3

Aleksandr-060686 [28]

Answer:

The correct answer is 12.446 feet.

Step-by-step explanation:

A ladder leans against a building forming an angle of 50° with the ground.

The base of the given ladder is 8 feet away from the building.

Let the length of the ladder that is to be found be x feet.

Thus we find the cosine of the angle of inclination.

∴ cos 50° = $\frac{8}{x}$

⇒ x = 12.446 feet

Therefore the length of the ladder is 12.446 feet.
