#4 the answer is 90° because it's a right angle,#3 is A because you have to follow P.E.M.D.A.S
Consider triangle WBG, where points W, B and G represent Weather Station, Balloon and Ground, respectively. This triangle is right with right angle at vertex G. The legs of this triangle are GB and GW, the hypotenuse is BW.
From the question you know that GB=4 km and GW=1 km. By the Pythagorean theorem,
![BW^2=GB^2+GW^2,\\ \\BW^2=4^2+1^2,\\ \\BW^2=17,\\ \\BW=\sqrt{17}\approx 4.123\text{ km.}](https://tex.z-dn.net/?f=BW%5E2%3DGB%5E2%2BGW%5E2%2C%5C%5C%20%5C%5CBW%5E2%3D4%5E2%2B1%5E2%2C%5C%5C%20%5C%5CBW%5E2%3D17%2C%5C%5C%20%5C%5CBW%3D%5Csqrt%7B17%7D%5Capprox%204.123%5Ctext%7B%20km.%7D)
Answer: nearly 4.123 km
Answer:
1st Question: The answer is 3.573
2nd Question: The answer is 3.971
Step-by-step explanation:
Answer:
2550 miles in 6 hours
Step-by-step explanation:
if you divide the miles and hours by each other you will get the m/ph (miles per hour)
3400 ÷ 8 = 425
now, that we know the plane travels 435 m/ph, then if we multiply it by 6 we will get the answer
425 × 6 = 2550
