Answer:

angle E, the measure is 135

angle J, the measure is 105

Step-by-step explanation:

Supplementary angles add up to 180 degrees.

We are to identify an angle that is supplementary to angle M form the given parallel line.

From the fist diagram, angle E and angle F are supplementary to angle M because they form adjacent angles on a straight line with angle M.

If angle m is 45 degrees, then the value of its supplement is 180-45=135

From the second diagram, angle H,angle J and angle P are supplementary to angle M.

If angle M is 75 degrees, the its supplement is 180-75=105

tangare [24]

Answer:

Option D - $\frac{1}{4}=\frac{x}{300}$

Step-by-step explanation:

Given : During the peak holiday season, a department store gift wrapper is expected to wrap a small gift box in 4 minutes.

To find : Which proportion could you use to find how many gifts can be wrapped at the same rate in 5 hours?

Solution :

We have given that,

In 4 minutes we wrap 1 box.

Let x be the number of gift wrap in 5 hours.

Convert 5 hours into minutes,

1 hour = 60 minute

5 hour = $5\times 60=300$ minute

i.e. In 300 minute we wrap x box.

The proportion defined the same rate is given by,

$\frac{1}{4}=\frac{x}{300}$

When we solve the proportion,

$x=\frac{300}{4}$

$x=75$

Therefore, Option D is correct.
