<h3>Answer: D.  (2, 21)</h3>

Explanation:

Imagine that your teacher wanted you to find the midpoint of -3 and 7 on the number line. To do this, you would add up the given values and divide by 2.

(-3+7)/2 = 4/2 = 2

The value 2 is right in the middle of -3 and 7 on the number line. This result is also the x coordinate of the midpoint since the values I used were the x coordinates of the original points.

The y coordinates are handled the same way:

(18+24)/2 = 42/2 = 21

The y coordinate of the midpoint is y = 21

Overall, the midpoint is (2, 21)

Option (d)

midpoint \: of \: the \: two \: points \:  =  (\frac{x1 + x2}{2}) \:  (\frac{y1 + y2}{2})

Let,

(-3,18) be (x1, y1). (7,24) be (x2,y2)

Substitute in this formula we get,

(\frac{ - 3 + 7}{2}) \:  (\frac{18 + 24}{2})

(\frac{4}{2}) \: ( \frac{42}{2})

= (2, 21)

Hey surveyor is measuring the distance across a small lake. He has set up his transit on one side of the lake 150 feet from a Pi
AleksAgata [21]

Answer: 87 feet

Step-by-step explanation:

The angle between the pilling is 60°

The adjacent side of the right angle is 150

So let the distance between the pilling be y, that is opposite side.

Opposite / adjacent = tan (60°)

y / 150 = tan (60)

y × tan (60°) = 150

Divide both side by tan (60°)

y = 150 / tan (60°)

y = 150 / 1.7321

y = 87 feet
