Answer:
x = 98
Explanation:
This is simple. It's an exterior angle.
We already have the angles that make up an exterior angle.
45 and 53.
So we just add it according to the rule.
So, it's 98.
You can also check this by finding the missing angle of the triangle.
So we know that 98 is for the first two angles and now we subtract that from 180 to find the missing angle of the triangle.
We get 82
So then since a line is 180 degrees, we subtract 82 from 180 to get x which is 98.
So your answer is still 98
