bernardo folds the 2 top corners of a rectanglular piece of paper to form 2 conguent triangles and an isosceles trapezoid. The triangles each have an angle that measures 65.
what are the measures of the 2 top angles in the trapezoid?

a. 25 and 25 because 65 + 25=90
b. 115 and 115 because 65 + 115=180
c.130 and 130 ecause 65 + 65=130
d. 25 and 65 because 65 + 25=90
