Hello!
This is a right isosceles triangle (45°-45°-90°). You can solve for the missing angle by simply subtracting 45° and 90° from 180° (sum of angles in a triangle equals 180°)
Since the triangle is isosceles, x and y are congruent because they are the legs opposite to the congruent angles.
In a right isosceles triangle, the hypotenuse is always the measure of one leg multiplied by
.

Solve for y:

y =
, which means that x is also 
Answer:

the difference is -5
- nth=a+(n-1)d
- a=253,n=49,d=5
- 253+(49-1)×-5
- 253+48×-5
- 253+(-240)
- 253-240=13
the 49th term is 13
