Atriangle has side lengths:
5,13,12 is this triangle a right triangle, an acute triangle of an obtuse triangle?

Answer

5^2 + 12^2 = 25 + 144 = 169 = 13^2

Therefore, it is a right triangle.

Step-by-step explanation:

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

good luck on your studies! : )
