Answer 1

#answer with quality

#BAL

Step-by-step explanation:

Triangle ABC is equaliteral, therefore each of its angle is 60°.

Now angleBCA=x° +angle CDA

Therefore 60°=x°+x° .......... (AC=CD)

2x°=60°

X°=60°/2

X°=30°

Hope this helps

Answer 2

Answer:

in equilateral triangle all the angles are equal i.e 60°

angle ACB+angle ACB=180

60°+x=180°

x=120°

∆ACD is an isosceles triangle

angle CAD=angle CDA

2x+120=180

2x=60

x=30
