Answer:
I believe it's B because they look very similar
Answer:
7 > y ≥ 3
Step-by-step explanation:
All the opposite angles are equal in a parallelogram:
so AB=DB shows it is an isosceles triangle:
so the two angles on the sides are congruent,
let x to be one of the angles:
2x+28=180
2x=152
x=76=∠A
∠A is opposite of ∠DCB so ∠DCB is 76° because of the parallelogram properties
A²+b²=c² according to pythogoras theorem.
a²=11.31²-8²
a²=127.91 - 64
=63.91
a=√63.91=7.99 = aprox. 8
