Given: m∠1 = 140°, find m∠5.

a) 40°
b) 90°
c) 130°
d) 140°

The correct option is D) 140°

Step-by-step explanation:

Consider the provided figure.    

When two parallel lines intersect by a transverse,  then the corresponding angles  are equal in measure.

Here the corresponding angles are:

m∠1 = m∠5 and m∠2 = m∠6

m∠3 = m∠7 and m∠4 = m∠8

We need to find the measure of angle 5. It is given that  m∠1 = 140°

From the above we know that m∠1 = m∠5, thus

m∠5 = 140°

Hence, the correct option is D) 140°
