Step-by-step explanation:

If the lower corner=70 degrees then the opposite side would also be 70 degrees since the opposite side is congruent

70 + 70 = 140

Top angle X= 180

180-140=40

X = 40

Answer:

X = 40 degrees

Step-by-step explanation:

since the line between the 70 and the x is congruent to the line between x and the empty corner, the empty corner is equal to 70, and 70 + 70 = 140 and if you know that the sum of all of the angles in a triangle is 180 degrees, you find x equals 40 degrees

hope this helps!!!! Thanks for the boatloads of points!!!
