Answer:
The answer is 145
Step-by-step explanation:
The diagonals of quadrilateral ABCD bisect each other so, the opposite angles are equal.
Angle A=35° and Angle C=35°
Let, Angle B=x and Angle D=x
so, angle A + angle B + angle C + angle D = 360°
=35°+35°+x°+x°=360°
=70°+2x=360°
=2x=360°-70°=290°
= x=290/2= 145°
So, the answer is 145 ° angle B and angle D = 145°
