Answer:
If a parallelogram has at least one 90 degree angle then its opposite angle is equal and also = 90 degrees.
The 2 remaining opposite angles add up to 180 degrees and since they must be equal, they must be 90 degrees each.
So, we have a quadrilateral with four 90 degree angles and is therefore a rectangle OR it could possibly be a square.
Step-by-step explanation:
Let x = the lions , so 3times the lions=monkeys
the 2 added=24
x+3x=24
4x=24
x=6
so there are 6 lions and 3times6 monkeys. 18 monkeys
36 is the value of 24xyz in those conditions.
Divide 3/5 by 2/3:
3
---
5 3(3)
------ = ---------- = 9/10 (answer). This is not a very satisfactory answer,
2 5(2) because 9/10 is a fraction. 2/3 is
--- larger than 3/5, so the answer would
3 be zero groups.
