Answer:
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°
