Wednesday: Solve for x (can't use decimals), must use the rules. Start by: What are the missing angles of this triangle?
What in the picture hints on the answer above?
X =
16

missing angle isosceles angle and side (a)

Pythagoras theorem

a²+a²=16²

a²=256/2

a=√128=11.3=11

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
