Find the value of x in the triangle shown below

x = sqrt(27)

Step-by-step explanation:

This is a right triangle, so we can use the Pythagorean theorem

a^2 + b^2 = c^2   where a and b are the legs and c is the hypotenuse

3^2 + x^2 = 6^2

9 + x^2 = 36

Subtract 9 from each side

9-9 + x^2 = 36-9

x^2 = 27

Take the square root  of each side

sqrt(x^2) = sqrt(27)

x = sqrt(27)

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
