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°

Make y the subject to the following questions

skelet666 [1.2K]

In this question it basically wants you to leave Y alone in a side of the equation.

In this case,
For 3y=c

$y=\frac{c}{3}$

For Ay=w

$y=\frac{w}{A}$

For Y/c=w
Y=cw

For y/a=2c
y=2ac

For a=y+p
y=a-p

For C=y-k
y=C+k
