Help please I really need help

see explanation

Step-by-step explanation:

The exterior angle of a polygon and its corresponding interior angle = 180°

Thus

a = 180° - 110° = 70°

b = 180° - 60° = 120°

c = 180° - 135° = 45°

d = 180° - 130° = 50°

e = 180° - 105° = 75°

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
