Question

Ray DE passes through the vertex of

Answer 1

The figure ABCD is a parallelogram

We have also gotten a 50 degree angle on the ray, using angles on a straightline = 180 degrees,

180 - 130 = 50 degrees

We labelled angle ADE as x.

ADE is a triagle. Sum of angles in a triangle = 180 degrees

So, 110 + 50 + x = 180

160 + x = 180

x = 180 - 60

x = 20 degrees.

Therefore, angle ADE = 20 degrees
