Answer:
132
Explanation:
Because you have a line that equals 180 degrees, you can subtract 180-148 to get the angle inside the bottom triangle, which is 32 degrees. Since that is part of a 90 degree angle, you can do 90-32, to get the angle in the bottom corner, which is 48 degrees. Using the Isosceles Side Triangle Theorem, the top most angle in the top triangle would also be 48. Since the line is a linear line which equals 180 degrees, you can do 180-48, to get 132, which is x.
