In δqrs, rs = 19, sq = 20, and qr = 18. which statement about the angles of δqrs must be true?

Scalene Triangle (Unequal Angles)

Step-by-step explanation:

A scalene Triangle is the one which has all three sides unequal. In the given triangle the three sides measure RS QR SQ are all unequal. A scalene Triangle has unequal angles. It has no line of symmetry. The angle opposite to the longest side is the greatest and so on.

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
