Answer:

I think it's x=-12 for the buttom one

Step-by-step explanation:

I think when you get open equations like these you would asume 1 is there so rewrite it as 2x + 25 = 1

so take the 25 away from 1. to do that we need to do the opisite of +

2x + 25 = 1

1 - 25 = -24

rewrite

2x = -24

take the 2 away. oppisite of mulitplication is division. so divide 2 by -24

-24 divided by 2 = -12

Hope this helps! Please mark as brainliest! Thanks! If you need me to solve the top one too, I'll do it! Just comment bellow. :D

Because the two angles shown are vertical angles, they are equal to each other.
Thus, we can write an equation to solve the problem as 4x-15=2x+25.
Now solve.
Add 15 to both sides.
4x=2x+40
Subtract 2x from both sides.
2x=40
Divide both sides by 2 to isolate x.
X=20
Now that we know the value of x, we can use that knowledge to solve for the unknown angles.
Substitute 20 for x in both equations.
4(20)-15
80-15
65
2(20)+25
40+25
65
The top and bottom angles are both 65 degrees, and x is 20.
Hope this helps!
