Answer 2

Answer:

$m\angle BDC = 95\degree$

Step-by-step explanation:

$In\: \triangle ACD\: \&\:\triangle BDC$

$m\angle A = m\angle B$ (given)

$\because m\angle A = 50\degree$

$\therefore m\angle B = 50\degree$

$m\angle ADC = m\angle BCD$ (given)

$\because m\angle ADC = 35\degree$

$\therefore m\angle BCD= 35\degree$

$In\: \triangle BDC$

$m\angle BDC = 180\degree - (m\angle B+m\angle BCD)$

(By angle sum postulate of a triangle)

$m\angle BDC = 180\degree - (50\degree +35\degree )$

$m\angle BDC = 180\degree - (50\degree +35\degree )$

$m\angle BDC = 180\degree - 85\degree$

$m\angle BDC = 95\degree$
