In the figure, p || q. you must prove that ∠4 is supplementary to ∠7. what is the reason for the highlighted statement in the proof?

substitution property of equality

for parallel lines cut by a transversal, corresponding angles are congruent.

congruent supplements theorem

vertical angles theorem

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
