Question

in the given figure at right, find angles acd and angle aed​

Answer 1

Step-by-step explanation:

In triangle ABC,

15+40+angle ACB = 180°( angle sum property)

angle ACB= 180 - 55

angle ACB = 125°

angle ACB + angle ACD = 180° ( linear pair)

angle ACD=180- 125

angle ACD =55

angleEDC + angle ACD = angle AED( external angle property)

52+55=angle AED

107°= angle AED

Therefore, angle ACD= 55° and angle AED= 107°

Answer 2

Answer:

acd=40+15=55

       180-55=125(the angle sum property of a triangle is 180 degrees)

       c=55

aed=73
