which of the following could be the measure of the angle below?
a. -180
b. -120
c.140
d.510

The measure of the angle indicated in the figure could be - 180° (Option a.)

Solution:

1. If we measure the angle in counterclockwise the sign is positive, then the angle could be:

180°, 180°+360°=540°, 180°+2(360°)=180°+720°=900°, ...

1. If we measure the angle in clockwise the sign is negative, then the angle could be:

-180°, -180°-360°=-540°, -180°-2(360°)=-180°-720°=-900°,...

Then, of the given options, the measure of the angle indicated in the figure could be -180° (option a.)

The answer is A

Step-by-step explanation:

$9.41

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
