Question

3. Find x in a ABC, if A = 53° and external angle ACD =106°
​

Answer 1

ACB=74°

ABC=53°

AS A triangle makes 180''

so ang ACD+ang ACB=180''

hence x+ 106'' = 180''

x= 106''

and remaining angles are 74'' and 53'' atriangle makes 180''

Answer 2

Step-by-step explanation:

find x in in a angle ABCD if if angle yay the pointer 53 degrees external angle angle ACD 1 06 degrees
