Question

Given quadrilateral ABCD≅quadrilateral EFGH, what is the value of x?

A. x = 75°

B. x = 80°

C. x = 100°

D. x = 105°

Answer 1

C) x = 100

Explanation:

75 + 105 + 80 + x =360

Answer 2

9514 1404 393

Answer:

C. x = 100°

Explanation:

The sum of angles in a quadrilateral is 360°. The figures are given as congruent (even though they don't look like it), so corresponding angles have the same measure.

80° +75° +x +105° = 360°

x = 100° . . . . . . subtract 260°
