Question

please answer for 100 points​

Answer 1

Step-by-step explanation:

a)(i)

Sol:

triangle AOD is an isosceles triangle because the diagonal of the rectangle divides the rectangle into two isosceles and congruent triangle

angle a=angle b (equal sides opposite angles are equal)

angle b=35°

now,

35°+35°+y°=180°(angle sum property)

70°+y=180°

y=180°-70°

y=110°

angle a=x(co - interior angles)

x=35°
