The volume of the bedroom is 11 x 10 x 10 = 1100 cubic feet.
The volume of the den is double, so 1100 x 2 = 2200 cubic feet.
Divide the volume of the den by the height, since it is the same as the bedroom, this will give you the area:
2200 / 10 = 220 square feet.
Two sets of numbers that could equal 220 are 22 x 10 or 22 x 11
The room can be 20 ft by 10 ft or 22 ft by 11 ft and the volume is 2200 cubic feet.
There's nothing here to choose from but it should be something like : q + d = 18; .25q + .10d = 2.85

Step-by-step explanation:
Sum of <span>supplementary = 180
180 - 35 = 145
145/2 = 72.5
so
one angle = 72.5
and
its supplement = 72.5 + 35 = 107.5
