You are building a dollhouse for your younger sister. The frame is in the shape of a pentagon. You want the two roof pieces to meet at a 52° angle, as shown in the model. What is the measure of the two congruent angles where the roof pieces meet the walls? m∠ABC = m∠EDC =

154 degrees

Step-by-step explanation:

The sum of the interior angles of a polygon is 540.

Hence to get the 2 angles,

52+90+90+2n = 540

232 + 2n = 540

2n = 308

n = 154
