Answer:
26 degrees
Explanation:
Triangle A:
So the triangle is 24 degrees and it is an isosceles triangle so the other 2 angles are equal. All the angles in a triangle add up to 180 degrees.
180-24=156 degrees
156 divided by 2 because of the 2 angles = 78 degrees
The angles in Triangle A are 78 degrees which means one corner of the Triangle X is 78 degrees as it is vertically opposite.
Triangle B:
B= 49 degrees and the triangle is isosceles as well. 49 x 2 for the other angle which would be the same is 98 degrees. We would then do
180 -98 = 82 degrees
This means the other angle in Triangle X is 82 degrees
Triangle X:
72 degrees is the top left angle and 82 degrees is the top right angle so you do 72+82= 154 degrees
180-154= 26 degrees
Hope this helps
