Step-by-step explanation:
we will use some tactics
triangle ABC is equilateral so it's every angle is 60
angle ACB = 60
angle CAB = 60
angle ABC = 60
now we find angles of other triangle
angle ACD = 180-60= 120 (forms a linear pair)
Angle CAD = X (iscoscales triangle have two angles of same measure)
X+X+120=180 (angle sum property of triangle)
2x+120=180
2x = 180-120=60
X = 60÷2
X = 30
