. This is the only problem requiring use of trigonometry. Two lasers, separated by 250 meters emit a beam of light to the top of a mountain which is due east of each laser. The angle of elevation of the laser beam
closest the mountain is 40°. The angle of elevation of the other laser beam is 35º. What is the height of
the mountain? [Hint: Consider using the law of sines and/or law of cosines.]

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.

thus, the first answer choice, y = sec x, is the correct one
