X=5
y=6
here’s how i got it:
-6x+6y=6
-6x+3y=-12
multiply the second equation by -1
you will get this:
-6x+6y=6
6x-3y=12
add them up and you will get
y=6
then substitute y in one of the equations and you will get x=5
Answer:
1440
Step-by-step explanation:
The sum of the exterior angles of a regular polygon of 10 sides = 360 deg. The sum of the interior angles of a regular polygon of 10 sides = 10*[180 - (360/10)] = 10(180–36) = 10*144 = 1440 deg.
The answer would be three
Answer:
Option A. 
Step-by-step explanation:
we know that
The tangent of angle ∅ is equal to divide the sine of angle ∅ by the cosine of angle ∅
so

therefore
The missing value is
