Answer:
Each x is equal to 39.
Step-by-step explanation:
Well, all of the angles in a triangle would add up to 180 degrees. So since this is an isosceles triangle, we now know that the two base angles are going to be congruent. We would do 180 minus 102 and that would get us 78. So x would be 39 because of 78 divided by 2.
Hope this makes sense! :)
