Find the measure of angle x 125

x = 125 degrees

Step-by-step explanation:

The vertical angles theorem states that two angles opposite to each other that are formed from 2 intersecting lines are congruent.

Therefore, angle x and the angle that is 125 degrees are congruent to each other.

So, x=125 degrees.

Hope this helps! :)

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
