Me . i dont understand this question.

y = 100°

Step-by-step explanation:

I can't see the full question, but I'm guessing you need to find the measure of angle y.

The total angle sum of a polygon can be calculated with the formula

T = 180°(n - 2)   where T is the total angle measure, and n i the number of sides.

For our shape, there are 4 sides, so n = 4.  Plug that in and simplify...

T = 180°(4 - 2)

  T = 180°(2)

      T = 360°

We are given 3 of the angles, so angle y is

y = 360 - 107 - 104 - 49

    y = 100°

the answer should be:

a. 3, 4, and 6

b. 18, 24, and 36

c. 4.8, 6.4, and 9.6
