Find the lettered angles.

a)  ∠a = 72°

∠b = 108°

b) ∠ = 56°

c) ∠m = 95°

Step-by-step explanation:

a) This shape is a regular polygon with 5 sides.

Therefore, sum of the interior angles = (5 - 2) x 180 = 540°

Therefore, ∠b = 540 ÷ 5 = 108°

∠a = 180 - 108 = 72°

b) The sum of the exterior angles of a polygon = 360°

Therefore, 55 + 63 + 52 + 44 + 90 + = 360

304 + = 360

= 360 - 304 = 56°

c) The sum of the exterior angles of a polygon = 360°

Therefore, 40 + 40 + 35 + 40 + 50 + 60 + m = 360

265 + m = 360

m = 360 - 265 = 95

step-by-step explanation:

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140
