Question

please solve it and identify what was wrong in solving it the first time

Answer 1

we have that

The sum of the interior angles in any triangle must be equal to 180 degrees

so

In the triangle ABE

A+B+E=180

substitute given values

60+55+E=180

E=65 degrees

so

mRemember that

m by vertical angles

so

mIn the triangle EDC

msubstitute given values

65+85+D=180

D=30 degrees

m
