Find x and y. give answer in insimplified radical form, not decimal.

Finding x,

We will use Pythagoras theorem to determine the value of x:

Finding y,

We have to determine the angle, at the bottom left of the bigger triangle.

Using sine rule,

To find the angle on the smaller triangle,

Finding the missing length of y,

So y = 2 + 8, y = 10

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
