Question

The lengths of x and y are shown in the figure below.

Which number line shows the closest approximate values of x and y?

Answer 1

The answer is x = 6.40312423743 y=12.8062484748

Answer 2

x = 6.40312423743 y=12.8062484748

Explanation:

To find the value of x, you must use the Pythagorean Therom.

a^2+b^2=c^2

5^2+4^2=c^2

25+16=c^2

41=c^2

Then find the square root of 41 so x = 6.40312423743.

Then to find y you must substitute the value of x in and use the triangle formula: 1/2(b)(h).

1/2(4)(6.40312423743)

y=12.8062484748
