Answer: 685 red marbles
Step-by-step explanation:
Lets set up a proportion:
x/1096 = 5/8
(For every 8 marbles, 5 of them are red)
Then we cross multiply
5480 = 8x
and divide!
so 685 marbles
1/2 (a+b)h
1/2 (a+16)14=132
8×14=112
14÷2=7
132-112=20
20÷7 =2.857142857
so then a= 2.86 (3sf)

In a trapezoid, two opposite sides are parallel and are called bases.
In this trapezoid, the top and bottom sides are parallel and are the bases.
The right side that intersects both bases is a transversal.
When parallel lines are cut by a transversal, same-side interior angles are supplementary. The measures of supplementary angles add to 180 deg.
x + 72 = 180
x = 180 - 72
x = 108 deg
