Which expression is equivalent to 18 − 20?

1 answer:

6 0

The answer is 18+(-20) because if if you were going to solve that equation you would use the absolute value of -20 and then the opposite of the sign giving you 18-20. Hope this helps:)

For this case we have that by definition $\pi$ equals 180 degrees.

We must convert 135 degrees to radians, then:

$135 * \frac {\pi} {180} =\\135 * \frac {3.14} {180} =\\\frac {423.9} {180} = 2.355$

Rounding off we have:

2.4 radians.

Answer:

2.4 radians
