From the given picture, we can see that 2 sides are congruen, then the given triangle is an isosceles triangle. In this triangle the base angles are congruent, so we can draw the following picture:
Now, since interior angles of any triangle add up to 180 degrees, we have

By combining similar terms, we get

Then, x is given as

Therefore, the answer is x=90 degrees
5 million is greater than 152000 because 5 million = 5,000,000 and that is larger than 152000 (only 152 thousand; 5 million is 5000 thousands)
