Question

Find the variables (arrows indicate that the lines are parallel​

Answer 1

Answer:

a = 110°

b=70°

Explanation:

a=110° , alternative angles

b+110=180...Linear pair

b=70

Answer 2

Answer:

The measurement of a=110°

The measurement of a=110°The measurement of b=70°

Explanation:

From the given figure,

Two parallel lines intersected by a transversal then

a=110°

(alternative interior angles are equal)

and

b+110°=180°

(linear pair)

=>b=180°-110°

=>b=70°

The measurement of a=110°

The measurement of b=70°
