Picture attached below
x =

82
98
262

x=82°

Step-by-step explanation:

1. The figure attached shows an inscribed quadrilateral, this means that the  vertices lie on the circle.

2. By definition, the sum of the opposite angles of an inscribed quadrilateral is 180°.

3. Then keeping this on mind, you can calculate the measure of x as following:

Solve for x:

4. Therefore, the answer is the first option.

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
