Answer:
The size of angle y is 126°
Step-by-step explanation:
From the diagram of the regular polygons, we have;
One side of each pentagon lies along a side of the octagon
The interior angle of the octagon > The interior angle of the pentagon
Each interior angle of a regular pentagon = 108°
Each interior angle of a regular octagon = 135°
Therefore, ∠ABC = 135° - 108° = 27°
Similarly, ∠BAC = 135° - 108° = 27°
Therefore, by triangle the angle sum theorem, we have;
∠y = ∠ACB = 180° - ∠BAC - ∠ABC = 180° - 27° - 27° = 126°
The size of angle y, ∠y = 126°.

Step-by-step explanation:
x-3x=4, x=2, plug 2 in for x y=-3*2 then, y=-6
Answer:
64 acres
Step-by-step explanation:
16*4=64
Multiply the acres per day by the number of days.
Change the dimensions to numbers of 0.5 inches: 3.5 is 7×0.5, 2.5 is 5, 1.5 is 3. The number of cubes needed is 7×5×3=105.
