Answer:
Please see the attached photo.
Step-by-step explanation:
The sum of the angles of a quadrilateral is 360°.

Given that x=30, the measure of ∠C is
∠C = (5/2)×30 +40 = 115
The appropriate choice is ...
D) 115°
Y = -4/5 x - 2
-9 = -4/5 x - 2
-4/5 x = -9 + 2 = -7
-4x = 5(-7) = -35
x = -35/-4 = 35/4
The answer is
x =<span> <span><span>−3/</span>17</span></span>
Step-by-step explanation:
28 + 19 + 13 equal 60%
therefore 40% divided by 60% multiply by 160 gives number of chicks
