What is the value of x?

x = 98˚

Step-by-step explanation:

The sum of the interior angles of a polygon with N number of sides is

180(N-2)

In your diagram, the polygon has 6 sides, so N=6

180(N-2) = 180(6-2) = 180(4) = 720˚

720 - 102 - 120 - 148 - 140 - 112 = x

x = 98˚

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
