Answer:
∠ ADC = 100° , ∠ DCB = 39°
Step-by-step explanation:
(3y + 7) and ( 3y - 13) are angles on a straight line and sum to 180° , so
3y + 7 + 3y - 13 = 180
6y - 6 = 180 ( add 6 to both sides )
6y = 186 ( divide both sides by 6 )
y = 31
Then
∠ ADC = 3y + 7 = 3(31) + 7 = 93 + 7 = 100°
and
∠ BDC = 3y - 13 = 3(31) - 13 = 93 - 13 = 80°
∠ BDC = 180° - (61 + 80)° ← angle sum in Δ BCD = 180°
= 180° - 141°
= 39°
It would depend on if the triangle was regular or irregular.So no if the triangle has different angles.If that is so then...
False.
