Lines & angles class 9

Model test paper class 9

A line intersects two parallel lines , forming eight angles . If one of the angles has measure a^@ , how many of the other seven angles are supplementary to it ?

Lines joining places of equal angle of declination are called

In a triangles ABC , angle A = x^(@) , angle B = (3x - 2) ^(@) and angle C = y^(@) , " Also " ,angle C - angle B = 9^(@) Find all the three angles of the Delta ABC .
