Answer 1

Remote interior angles are the two angles that are not supplementary with the exterior angle of a triangle.
<c and <a are the remote interior angles of <y
<a and <b are the remote interior angles of <d
In a tight triangle, one angle measures 90°. All triangles add up to 180° according to the Triangle Sum Theorem. Using the measure of 50°, we can find the measure of the other angle.
90+50=140
180-140=40
The measure of the other angle is 40.
I hope I helped :)
