8. For the following problem, given two angles of a triangle, find the measure of the third angle. $82^{\circ}$ and $53^{\circ}$ $45^{\circ}$ $37^{\circ}$ $90^{\circ}$ $63^{\circ}$

Step 1 ：Given two angles of a triangle are $82^{\circ}$ and $53^{\circ}$

Step 2 ：The sum of the angles in a triangle is always $180^{\circ}$

Step 3 ：Subtract the sum of the two given angles from $180^{\circ}$ to find the third angle

Step 4 ：So, the measure of the third angle is \(\boxed{45^{\circ}}\)
