What is the measure of angle x don’t know if it’s right answer asap

Hey!
you are correct because this can be proven by alternate interior angles! This means that the 60 degree angle is also congruent to the angle with the x and 25 degrees. Also if you move the 60 degree angle up on to of the line with the other arrow, you will notice that the 60 degree angle and the x and 25 degree angle are vertical angles which means they are congruent. 
So you would do x+25 = 60
subtract 25 from both sides and you get that x=35
Hope this helps!

Hello!

60° and 25°+x° are opposite interior angles. Therefore they are congruent and have the same angle measures. Therefore we subtract to find x.

60-25=35°

Our answer is B) 35°

I hope this helps!
