Mr.soto drew a design for a quilting pattern. The design is made up of 5 congruent isosceles trapezoids as shown below. What is the measure, in degrees, of angle y?

bobpursley,
Do you really think we can see this (with our crystal ball)?

juli,
•find the measure of one of the interior angles
180(3)/5 =108
•y is NOT the exterior angle
•use the formula:
360a=2y
*where a= the measurement of 1 of the interior angles which is 108 in this case.
•so it would be:
360108=2y
252=2y
252/2=y
126=y
•so y=126
