Answer:

Step-by-step explanation:

First count the number of sides. There are 6 sides.

Now use the formula

(n - 2) * 180  To determine the total of all 6 angles.

(6 -2) * 180 =

4 * 180 = 720

Is that a 9 in x + 9 [lower left]? I'll assume so. Edited to show it was a 4.

x + 4 + 120 + x + 50 + 140 + 112 + x = 720     Combine

3x + 4 + 120 + 50 + 140 + 112 = 720

3x + 426 = 720                                                Subtract 431 from both sides

3x = 720 - 426                                                 Combine

3x = 294                                                          Divide by 3

x = 294/3

x = 98
