Find the value of a. Then find the angle measures of the polygon. a =

(2aº caº
a
Sum of angle
measures: 360°

In the given quadrilateral, two angles measure 60° and other two angles measure 120°.

Step-by-step explanation:

As we know sum of all interior angles of a polygon with 'n' sides is,

Sum of interior angles = (n - 2) × 180°

                                     = (4 - 2) × 180° [for a polygon with n = 4]

                                     = 360°

a + a + 2a + 2a = 360°

6a = 360°

x = 60°

Measure of angles = a° = 60°

And angles having measure = 2a° = 2(60)°

                                               = 120°

Therefore, in the given quadrilateral, two angles measure 60° and other two angles measure 120°.

c. prove the lengths are the same.

step-by-step explanation:

you need to prove the segments are congruent. congruent segments have the same length. find the lengths of the segments using the distance formula, and compare them.

answer: c. prove the lengths are the same.
