Same-side interior angles, which are shown here, are supplementary, which means that they add up to 180 degrees.

5a + a = 180

6a = 180

a = 30 degrees

Step-by-step explanation:

2x+5.2 + 3x+ 1.2 +2x+6.2= 180

7x+ 12.6=180

7x 12.6 - 12.6=180 -12.6

7x = 167.4

x = 23.914

should equal 60

Answer:

374.1

Step-by-step explanation:

Area of Hexagon = $\frac{3\sqrt{3} }{2} * a^{2}$

The ' a ' is the side length.

So now we just plug in the values

$\frac{3\sqrt{3} }{2} *12^{2}$ = 374.12
