Answer 1

Answer:

A.)  x=25

Step-by-step explanation:

since these are vertical angles, that means they equal the same

  -  75= (4x-25)

add 25 to both sides in order to isolate 4x

  -   100=4x

divide both sides by 4 in order to isolate the x

  -    25=x or x=25

Answer 2

Answer:

$\huge\boxed{x = 25}$

Step-by-step explanation:

In these two lines that intersect, we can see that 4 angles are opposite from each other. This means that they are vertical angles and therefore equal. 2 of these angles have values next to them, which happen to be across from each other.

Based on this, we know that they are equal. If we write this as an equation, we can solve it to find the value of x.

75º = (4x - 25)º

Add 25º to both sides of the equation

100º = 4x

Divide both sides of the equation by 4 to isolate x

x = 25
