Question

8. Find the measurement of the biggest and the smallest angle in the adjacent
figure
​

Answer 1

Answer:

Step-by-step explanation:

∠1+∠2+∠3+∠4 = 360°

2x+30°+3x-70°+3x+40°+5x-30° = 360°

13x - 30° = 360°

13x = 390°

x = 30°

biggest angle i.e. ∠4⇒ 5x-30° = 120°

smallest angle i.e. ∠2⇒3x-70° = 20°

Answer 2

Answer:

smallest angle is 2
