Mathematics
1 answer:
oksian1 [2.3K]2 years ago
8 0

Answer:

x = 8

Step-by-step explanation:

There are two ways of answering this:

1.)Supplementary Angles/Linear pair:

(5x- 15) + (20x - 5) = 180°

25x - 20 = 180

25x - 20 +20 = 180 + 20

25x = 200

x = 8

2.) Vertical angles theorem:

(5x - 15) = (3x + 1)

5x - 3x -15 + 15 = 3x - 3x + 1 +15

2x = 16

x = 8

Illusion [34]

Answer:

No solutions.

Step-by-step explanation:

Both equations have the same slope, but are separated by virtue of their different values of b, the y-intercept.  The same slope means they are parallel lines.  Since the y-intercept is different, they do not overlap.

As they say, "Parallel line have a lot in common.  Too bad they'll never meet."

In the given figure, measure HK= 50° and measure GKL is 50° which statement is true?
Minchanka [31]

Answer: A

Step-by-step explanation:

The answer is a because the measure of angle KGH is 25 degrees since it is an inscribed angle. Angle GKJ is 130 degrees because angle GKL is 50 degrees. Therefore angle J is equal to 25 degrees which makes the triangle an isosceles triangle since angle J and angle KGH are equal to one another.
