345 degrees to a radion​
miv72 [106K]

We convert degrees to radian by multiplying by  (

\frac{\pi}{180})

=  (345)  ×  (  \frac{\pi π}{180} )

=  (\frac{345}{180})  ×  (π)

=  1.9166π

=  1.9166  ×  3.14

=  6.018 rad

≈  6.02 rad

What is the solution of the system? Use elimination.
Anit [1.1K]
Note that if we add each side of the 2 equations, y will cancel out:

-12x-y+(17x+y)=6+4

5x=10

x=2


Substituting x=2 in either of the equations, we find the value of y.

Let's use the first equation:

-12x-y=6

-24-y=6

-y=24+6

-y=30, so y=-30.

Thus, the solution is (2, -30)
