Step 1: Identify triangle type. The triangle shown is isosceles because two sides are marked as equal. Step 2: Find base angles. In an isosceles triangle, the angles opposite equal sides are equal. Step 3: Sum of angles in triangle. The sum of angles in a triangle is always 180. Step 4: Substitute equal angles. Since x = y, we substitute y with x. Step 5: Solve for x. Subtract 55 from both sides. Step 6: Calculate x. 180 minus 55 equals 125. Step 7: Find value of x. Divide both sides by 2 to get the value of x. Step 8: Final Answer. Both base angles are 62.5 degrees because the triangle is isosceles and the sum of angles is 180 degrees.
