In the triangle below, which of the following best describes Xy?
Y
40°
40°
A. Angle bisector
B. Median
C. Altitude
O
D. Perpendicular bisector

Answers

Answer:

option A is correct answer of this qn

The word which best describes XV is Angle Bisector.

What is Triangle?

A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.

Sum of the interior angles of a triangle is 180 degrees.

Given is a triangle XYZ.

Here a line segment is drawn from the vertex X to the opposite side YZ.

Median is the line segment joining the vertex of a triangle to the mid point of the opposite side.

Here, it is not given that, YV = ZV, so it is not median.

Altitude is the perpendicular line joining the vertex to the opposite side.

Here, it is not given the line is perpendicular. so it is not altitude.

Perpendicular bisector is a line that bisects the opposite line in to right angles. It is also not given.

Angle bisector is a line which divide the angle from which the line is drawn. here it is given that both angles equal to 40°.

So the line is angle bisector.

Hence the correct option is Angel Bisector.

Answer:

  y +2 = -1/2(x -7)

Step-by-step explanation:

The line PQ has a rise of 6 units for a run of 3 units, so its slope is ...

  m = rise/run = 6/3 = 2

A line perpendicular to PQ will have a slope that is the opposite reciprocal of that, so ...

  -1/m = -1/2

We have the slope of the desired line, and a point it needs to pass through, so we can use the point-slope form of the equation of a line.

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

An equation for the desired line is ...

  y +2 = -1/2(x -7)

__

This can be rearranged to other forms.

  y = -1/2x +3/2 . . . . . slope-intercept form

  x +2y = 3 . . . . . . . . . standard form

Answers

Answer:

-15 5/6

Step-by-step explanation:

Combine the given terms (through addition and subtraction).

14 7/8  -  15  -  5/6  -  14 7/8

Identify the LCD:  It is 24

Therefore we have:

14 21/24 - 15 - 20/24 - 14 21/24

Combining the whole numbers, we get

14 - 15 - 14, or -15

and combining the fractions, we get

21 - 20 - 21

----------------- = -20/24

       24

and so we have -15 - 20/24, or -15 - 5/6, or -15 5/6
