What is the measure of ZCED in degrees?

The correct option is A.

A) m, because ΔABC ~ ΔEDC

Step-by-step explanation:

Consider the both triangles.

<B = 60°

<D = 60°

<B and <D are congruent

<ACB = 90°

<DCE = 90°

<ACB and < DCE are also congruent.

As sum of the angles of triangle is 180°

<A = 180° - <ACB - <B

<A = 180° - 90° - 60

<A = 30° = m

<E = 180° - <DCE - <D

<E = 180° - 90° - 60°

<E = 30°

As m = 30°

<E = <CED = m

As segment AD cuts segment BE, which results in formation of two triangle, and as all angles of both triangles are equal, both triangles are similar.

pi x^2

step-by-step explanation:

pi times x squared

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)
