Question

If QAP = 35, ACD = 100 , find ABC, BAC and ACB.​

Answer 1

Answer:

Angle BAC = 35 degree

Angle ACB = 80 degree

angle CBA = 65 degree

Step-by-step explanation:

Angle BAC = angle QAP. ( Vertically opposite angles)

Angle BAC = 35 degree

Angle ACB + angle ACD = 180. (sum of angles on a straight line)

Angle ACB + 100 =180

Angle ACB = 80 degree

sum of angles of a triangle is 180 degree

Angle BAC + angle ACB +angle CBA = 180 degree

35 degree + 80 degree + angle CBA = 180 degree

115  degree + angle CBA = 180 degree

angle CBA = 180 degree - 115 degree

angle CBA = 65 degree
