A line segment on a number line has its endpoints at -9 and 6. Find the coordinate of the midpoint of the segment.. . A. 1.5. *

Lyrx [107]

By definition, the midpoint is given by:
$m = (\frac{x1+x2}{2}, \frac{y1+y2}{2})$

Part A:
For the line segment we have:
$m = \frac{-9+6}{2}$
$m= \frac{-3}{2}$
$m = -1.5$
Answer:
the coordinate of the midpoint of the segment is:
B. -1.5

Part B:
For line segment HX we have:
$m = (\frac{-1+7}{2}, \frac{3-1}{2})$
$m = (\frac{6}{2}, \frac{2}{2})$
$m = (3,1)$
Answer:
the coordinates of the midpoint of the segment is:
A. (3,1)

In a 30-60-90 triangle, the length of the hypotenuse is 30. Find the length of the shorter leg

hammer [34]

Answer:

Option A is right

Step-by-step explanation:

Given is a triangle (right angled) with other degrees as 30 and 60.

The length of hypotenuse = 30

We have to find the length of shorter leg.

We know that in a 30-60-90 triangle, the length of shorter side is always half the length of the hyptenuse.

In 30-60-90 triangle, opposite side of smaller angle/hypotenuse =1/2

Using the above we get

the shorter side = 1/2 (hypotenuse) = 1/2(30) = 15

Hence answer is 15
