Question

find all the angles of the triangle ABC ​

Answer 1

Step-by-step explanation:

angle BAC=35(vertically opposite angle)

angle BCA=180-100=80(LINEAR PAIR)

BAC+BCA+ABC=180

35+80+ABC=180(INTERIOR ANGLES OF A TRIANGLE IS EQUAL TO 180)

115+ABC=180

ABC=180-115

ABC=65

BAC=35

BCA=80

Answer 2

Answer:

angle BAC = 35°[Vertically opposite angle of angle QAP (30°)

Angle ACB=80°[angle ACD - angle ACB (exterior angle property)]

angle ABC =180-(35+80)

=65 °(sum of interior angles of a ∆ is 180)

Step-by-step explanation:

hence proved.
