the number of points a plain contains is 3
16/25 is the highest, because if you multiply it by four you get 64/100, and the rest of the fractions are negative.
Answer:
Since it's a straight line, hence the sum of both angles must be 180°
now,
(2y + 1) + (5y - 3) = 180°
now by solving above equation u can get the value of y!

Answer:
The angle of elevation is approximately 
Step-by-step explanation:
Notice that the two pieces of information given: "400 ft away from a building", and building that is "850 ft tall", can be regarded as the two legs of a right angle triangle (see attached image).
Then the angle 
that we are trying to find (the angle of elevation) can be found by using the arc-tangent function:
