Your answer would be B. Here is how to approach this problem. Since this polygon has 6 sides then the total sum of degrees should be 720. (6-2)(180)= 720 That is the formula to determine the total degrees of a polygon like a triangle. (3-2)(180)=180 Since you know that all of them equal 720 you can make this equation. 6x+4x+105+130+120+125=720 Simplify and you get 10x+480=720 Subtract 480 on both sides 10x=240 Divide by 10 on both sides x=24 So plug 24 back into the missing angles 6 x 24= 144 4 x 24= 96 Again, it is answer choice B.
