Answer:
Step-by-step explanation:answer is 55 degrees
alright first of all u gotta prove that both the triangles ABD and ADC are congruent
In triangle ABD and ADC we have
AD=AD ( COMMON)
AB=BC(GIVEN)
BD=DC( BECAUSE OF MEDIAN)
by SSS congruency traingles ABD and ADC are congruent and thus
angle ABD = ADC
angle BAD = DAC
since angle ABD IS 35 so ACD is also 35
we know that sum of all angles is 180 so
ABC + ACB + BAC= 180
35 + 35 + BAC =180
BAC = 110 since BAC = BAD + DAC and BAD = DAC
SO 2BAD = 110 THUS BAD = 55

Answer:
Hey army
Love ur dp btw
ABC is an isosceles triangle since AB=AC, ∠B=∠C=35°
∠A=110° (∵∠A+∠B+∠C=180 )
In an isosceles triangle, median (AD) to the base BC is the angular bisector of ∠A
Hence, ∠BAD=55°
