Answer:

Step-by-step explanation:

If a quadrilateral is inscribed in a circle with all four edges touching the circumference of the circle, then the opposite angles are supplementary. This means that the sum of the opposite angles is 180 degrees. Therefore,

Angle B + angle D = 180

Angle A + angle C = 180

3x + x + 20 = 180

4x = 180 - 20 = 160

x = 160/4

x = 40

Angle A = 2 × 40 + 78 = 158 degrees

Angle B = 3 × 40 = 120 degrees

Angle C = 180 - 158 = 22 degrees

Angle D = 40 + 20 = 60 degrees

alexgriva [62]
There is only one solution because it is a linear equation.
3x - 6 = 22 - x
3x + x = 22 + 6
4x = 28
X = 7

PLZZZZ HELLPPP MEEE GET ANSWER
nadya68 [22]

Answer:

<em>See above photograph</em>

Step-by-step explanation:

This is how your graph will look like with an x-intercept of [−5, 0] (will not see, according to the scale, but on my device, you can), and a y-intercept of [0, 50]. The way to figure out all the coordinates upon this scale is to simply create a y-x value chart. Plug in each input value [x-value] to get your output value [y-value]:

<u>x|y</u>

0|50

1|60

2|70

3|80

4|90

5|100

6|110

7|120

8|130

9|140

10|150

11|160

Then, you simply just draw your line based of this chart.

I am joyous to assist you anytime.
