Question

please tell me this solution​

Answer 1

Answer:

Step-by-step explanation:

ANGLE BDA=90 degree

Angle sum property-

90'+55'+angle BAD=180'

135'+angle BAD=180'

angle BAD=180'-135'

angle BAD=35'

For angle CAD-

BAC is perpendicular-

35'+angle CAD=90'

angle CAD=90'-35'

angle CAD=55'

For angle ACB-

Angle sum property-

90'+55'+angle ACB=180'

145'+angle ACB=180'

angle ACB=180'-145'

angle ACB=35'
