An observer (o) is located 500 feet from a school (s). the observer notices a bird (b) flying at a 39° angle of elevation from his line of sight. how high is the bird flying over the school? you must show all work and calculations to receive full credit.

a right triangle is shown with one leg measuring 500 and another leg measuring h with an angle across from it measuring 39 degrees.

i just took the test, the correct answer is .. 31.5 in.

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
