Question

In the paper airplane shown

Answer 1

Answer:

∠GHE = 55°

Step-by-step explanation:

ABCD is a quadrilateral (4 sided figure). We know that the sum of the interior angles (4 angles) of a quadrilateral in 360°.

Thus, A + B + C + D = 360

we know b = c = 90 and a = 125, thus we can find D.

125 + 90 + 90 + D = 360

305 + D = 360

D = 360 - 305 = 55°

Note: since Quadrilateral ABCD is congruent to Quadrilateral EFGH, then the measure of D is equal to measure of H (Angle GHE). Thus

∠GHE = 55°

2nd answer choice is correct
