Answer:
159.35 meters
Step-by-step explanation:
-We use the law of Sines to calculate the distance to the plateau's base.
-The angle of depression (90-20=70°) corresponds to this distance:

Hence, the distance to the base is 159.35 meters

Answer:
1/3
Step-by-step explanation:
There are 6 lines on the way to 1 whole number. that means that each line is 1/6. A is 2/6 on the number line. 2/6 simplified is 1/3.
The correct answer is C. 4.
Typically, we look to multiply by the bottom number (the denominator) in order to get fractions to cancel out. If we multiply 1/6 by 6, we get just 1, which is why we do it.
In this problem, you have two different denominators, 2 and 4. If you multiply them all by 2, the term -3/4m will still be a fraction.
-3/4m * 2 = -3/2m
As a result, we must try 4 instead. This causes all of them to cease being a fraction. Even the one with 2 as a denominator.
-1/2 * 4 = -2
