Answer:
angle DEC = 110
Step-by-step explanation:
In triangle BDC
angle B + angle D +angle C =180
angle B =180-100-25
angle B = 55
By angle sum property
In ABC
angle A+angle B + angle C =180
angle C =180-55-55
angle C = 70
angle DCE = angle BCE- angle BCD
angle DCE = 70 -25=45
angle DCB = ANGLE EDC (:. ALTERNATIVE ANGLES)
IN triangle CED
angle C+ angle D+ angleE = 180
angle C = 180 -70
angle DEC = 110
