Three angles measures add to 180° and have the following measures: mLACB = (2 + 15) ° , m/BCD = (2 + 48) °, and m LDCE = 13°.
What is the measure of LBCD? (1 point)
The measure of LBCD is 180° - (mLACB + m/BCD + m LDCE).
mLACB = (2 + 15) ° = 17°
m/BCD = (2 + 48) ° = 50°
m LDCE = 13°
Therefore, the measure of LBCD is 180° - (17° + 50° + 13°) = 100°. Answer: \boxed{100}.
