For 15- it takes him 30 minutes to run.
8 divided by 3 is 2 2/8
8 divided by 60 is 0.1333
That's about 0.6 of a hour.
That's 36 minutes!
Looking at the triangle, we see that the angle 29.7 deg and the "adjacent side" length 20 ft are given. Our job is to find the "opposite side," which is the height of the tree.
Write out the tangent function: tan 29.7 deg = opp side / adj side
Then tan 29.7 deg = (opp side) / (20 ft).
Solving for the length of the opp side:
opp side = (20 ft)(0.57) = 11.41 feet. This is also the height of the tree.
The answer would be "B", 246 m2.
The next bigger hundredth is 1,199,495.01 .
The next smaller hundredth is 1,199,494.99 .
The number in the question is exactly midway in between those. Neither of them is closer to the number than the other one is. So the number is already at the nearest hundredth.
