Find the measure of each interior angle of a regular convex dodecagon. Show equations and all work that leads to your answer.
Arada [10]

The exterior angles to any convex polygon sum to 360 degrees in measure, so that for a regular dodecagon (12-gon) each exterior angle has measure

\dfrac{360^\circ}{12}=30^\circ

Exterior angles are complementary to interior angles, which means each interior angle has measure

180^\circ-30^\circ=\boxed{150^\circ}

The function f(x) = 2x2 + 3x + 5, when evaluated, gives a value of 19. What is the function’s input value?
Brums [2.3K]
The function's input value is 2.

f(x) = 2x² + 3x + 5
f(x) = 2(2)² + 3(2) + 5
f(x) = 2(4) + 6 + 5
f(x) = 8 + 11
f(x) = 19
