> B
A
350
С
53°
D
E​

Answer 1

Answer:

I will be denoting an angle just by three letters.

In the figure,

BAC and CED are alternate angles.

So, BAC = CED = 35°

For ACD, the two interior opposite angles are CED and CDE.

As exterior angle = sum of interior opposite angles,

ACD = CDE + CED

= 53° + 35°

So, ACD = 88°

Thus measure of angle ACD is 88°
