To find the measure of angle BCD, we can use the fact that the sum of the three angles is equal to 180°.
So, we have the equation: (x+15) + (x+48) + 13 = 180°
Combining like terms, we get: 2x + 76 = 180°
Subtracting 76 from both sides, we get: 2x = 104°
Dividing both sides by 2, we get: x = 52°
Therefore, the measure of angle BCD is x+48 = 52°+48° = 100°.
So, the correct answer is: 100°.
