Answer:
- 984 adults
- 281 teens
- 492 children
Step-by-step explanation:
Multiply the total by the corresponding percentage to find the number. We assume the percentages have been rounded, so some adjustment is needed in the result of the multiplication.
{adults, teens, children} = 1757 × {.56, .16, .28} = {983.92, 281.12, 491.96}
≈ {984, 281, 492}
The visitors included 984 adults, 281 teens, and 492 children.
To find x, substract 72 and 78 from 180 since all triangles are 180°
180 - 72 - 80 = 30
So x = 30
To find y, x and y equal 180 so subtract 30 from 180
180 - 30 = 150
y = 150
x = 30, y = 150
