Answer:

x = 117°

Step-by-step explanation:

First, find the angle the supplements angle 101°.

Using the supplementary angle (angles that add up to 180°).

180° - 101° = 79°

We now have two interior angles inside the triangle, 38° and 79°.

A triangle's total angle measures 180° in total.

So,

? + 38° + 79° = 180°

? + 117° = 180

? = 180° - 117°

? = 63°

Now like the first step we did, use the supplementary angle theorem to find x.

x + 63° = 180°

x = 180° - 63°

x = 117°

Answer:

x = 117 degrees

Step-by-step explanation:

A triangle has 180 degrees in total.

A straight line is also 180 degrees in total.

180 - 101 = 79

Angles inside the triangle

79 + 38 = 117

180 - 117 = 63

63 degrees is the missing angle

x = 180 - 63

x = 117

Answer:

x= -2, x = 5

Step-by-step explanation:

$\sqrt{5x+11}-1=x$

$\sqrt{5x+11}=x+1$

$5x+11=(x+1)^2$

$5x+11=x^2 + 2x + 1$

$0=x^2 + 2x + 1-5x-11$

$0=x^2 -3x-10$

$0=(x+2)(x-5)$

x= -2, x = 5

(25 points) Which list contains only rational numbers?

Shkiper50 [21]

A rational number is any number that can be wrote as a fraction (p/q). A rational number is the quotient or fraction of two integers. It is seen as a ratio of two integers as well. Repeating/terminating decimals are also rational numbers as they can be shown as the ratio of two integers. (p/q) the fraction, will have both the numerator and denominator being whole numbers.

what we can do: Look at each number in the sequences and see which will have only rational numbers. A: 0 is rational, 1/2 is rational because it is a ratio of two integers, 1.5 is rational because it can be written as 3/2, and 2.82843 is rational because it can be wrote over one as a ratio of two integers.

So A is the only list that contains only rational numbers.

Translate the shape A three squares right and one square down.What are the coordinates of the vertices of the image?

nataly862011 [7]

If the shape A is translated four squares right and two squares up, the resulting coordinate point will be at (-2, 5), (-2, 2) and (0, 2)

<h3>Translation of coordinates</h3>

Translation is a transformation technique of changing the position of an object on the xy plane

Given the coordinates of the vertices (1, 4), (1, 1), (3,1)

If the shape A is translated three squares right and one squares up, the resulting coordinate point will be at (-2, 5), (-2, 2) and (0, 2)

Note that 4 was subtracted from the x-axis and 2 added to the y-coordinates.

Place a point D along AC such that BD is an altitude of ABC. Using coordinate algebra, find and record the coordinates of point

aliya0001 [1]

Sample answer from Edmentum

Answer:

D = (9.6,0). AC is horizontal with y=0 at all points on AC. Also, because BD is an altitude, it forms a right angle with AC, so BD is a vertical line. For all points on BD, x= 9.6.

Hope this helps, have a good day (:
