Question

Help with Math please!

What is the measure of angle CED?

p over 2, because Triangle ABC is congruent to triangle DCE
p + 70 degrees, because Triangle ABC is similar to triangle DCE
110 degrees − p, because Triangle ABC is congruent to triangle DCE
p, because Triangle ABC is similar to triangle EDC

Answer 1

∠CDE=∠CAB ∠ABC=∠CED
they are alternate interior angles

∠CAB=70 ,∠CED=70=p

Answer is D

Answer 2

The answer is P, because if both triangles are right angled and have the angle of 70°, then because angles in a triangle equal 180° you can say that they will be the same as 70 + 90 = 160, and 180 - 160 = 20, which is the same steps for both triangles. I hope this helps! Let me know if I need to explain it further or anything :)
