Answer:
Vertical angles
x=25
Step-by-step explanation:
Adjacent angles are angles that are next to each other. Vertical angles are angles that are opposite each other.
In this problem, the angles are opposite each other. Therefore, they are <u>vertical</u> <u>angles.</u>
Since they are vertical angles, they are congruent, or equal. So, we can set them equal to each other and solve for x.
75=4x-25
To solve for x, we have to isolate x. First, move all the constants to the same side, by adding 25 to both sides.
75+25=4x-25+25
75+25=4x
100=4x
Now, 4 and x are being multiplied. To undo this, divide both sides by 4.
100/4=4x/4
100/4=x
25=x
The angles are vertical and x=25
A. 3x+4y+2=0 ----------linear
B. X= 2,4,6,8 Y=1,5,15,30 -------nonlinear
C. You have a secret that you tell to one person. Every hour, each of the people that know the secret tells one person. The number of people who know is N, and t is the number of hours since you told the first person. Is N a linear function of t? ----------linear
You must set up an equation for this problem. Your equation is 10=0.2x. If we divide both sides by 0.2, we get 10/0.2=x which equals x=50. This means your number is 50 because 0.2*50=10.
