Answer:

x = 30

Step-by-step explanation:

The 2 given angles are same- side exterior angles. That is they are on the same side of the transversal and outside the parallel lines.

same- side exterior angles are supplementary, thus

x + 12 + 3x + 48 = 180, that is

4x + 60 = 180 ( subtract 60 from both sides )

4x = 120 ( divide both sides by 4 )

x = 30

Answer:

(3x+48)+(x+12)

=4x+60

4x+60=180

4x=120

x=30

A parachutist's speed during a free fall reaches 207 kilometers per hour. What is this speed in meters per second? At this speed
Mamont248 [21]
<span>The speed is 57.5 m/s and the parachutist will fall 1150 m in 20 seconds.

Explanation<span>:
We start out with the ratio 207 km/1 hr.

We know that 1 km = 1000 m; this means 207 km = 207*1000 = 207000 m. This gives us 207000 m/1 hr.

We know that 1 hr = 60 minutes, so we have 207000 m/60 min.

We also know that 1 min = 60 seconds, so 60 min = 60*60 = 3600 sec; this gives us 207000 m/3600 sec.

Dividing this, we get 57.5 m/s.

In 20 seconds, the parachutist will fall 57.5(20) = 1150 m.</span></span>
