C. 180
D. 292
2 answers:
Answer: B. 164
The value of y =30
The value of CD = 164
Step-by-step explanation:
Properties of isosceles trapezoid:
Two sides are parallel. The opposite non-parallel sides are equal. The diagonals are equal.
Given: ABCD is an isosceles trapezoid with diagonals that intersect at point P. AB || CD
⇒ BC= AD [opposite non-parallel sides]
AC=BD [ Diagonals are equal]
Since and
The value of CD =
I think its A or B not sure(educated guess)
