Answer:
Angle D equals 80 degrees.
Since both triangles and angles are congruent, you can use triangle ABC to find the measure of CDE.
ABC has to equal 180 degrees so that means that 30 + 70 + <B = 180
add: 100 + <B = 180
Subtract <B = 80
Angle B equals 80 degrees which also means that Angle D equals 80 degrees.
What’s the the math problem? I don’t see it..
I think it’s Quadrant III
