find the measurement of the biggest and the smallest angle in the figure give​

Answer 1

Answer:

sum of all angles = 360°

2x + 30 + 3x - 70 + 5x - 30 + 3x + 40 = 360

2x + 3x + 5x + 3x + 30 - 70 - 30 + 40 = 360

13x - 30 = 360

13x = 360+30

13x = 390

X = 390/13

X = 30

now u can find the angles.
