Answer 1

Answer:

Angle ACD = 115

Step-by-step explanation:

In Triangle ABC

Angle ACB = 180 - (Angle ABC + Angle ACB)

                  =  180 - ( 60 + 55)

                  = 180 - (115)

                  = 65

Angle ACD = 180 - 65 (Sum of Linear Pair = 180)

                   = 115

• Remember

1. The sum of all internal angles of a triangle is always equal to 180°. This is called the angle sum property of a triangle.
2. The sum of the length of any two sides of a triangle is greater than the length of the third side
3. Angles on a straight line adds upto 180 °
