Answer:

Step-by-step explanation:
Triangle MRN is created by folding an equilateral triangle by half. Since triangle MRN is right triangle, the equilateral triangle must be folded along the height drawn to one side.
In equilateral triangle with side length of a units, the height is
and the height is greater than half the side because

The leg with length x units has the smaller projection (2 units long) than the leg with length y units has (6 units long).
This means the leg with length y units is the height of the equilateral triangle. If the leg with length y units is the height of the equilateral triangle, then the hypotenuse MN = 8 units is the side of the equilateral triangle and lex with length x units is half the side, so x = 4 units.
By the Pythagorean theorem,

Answer:
Step-by-step explanation:
9m-3(m+6)=2(m+1)
9m - 3m - 18 = 2m + 2
6m- 18 = 2m +2
4m = 16
m= 4
Answer:
Step-by-step explanation: it doesn't matter if it says even or odd it's the same formula
Because think if you start with 1 to get 3 you add 2
If you start with 2 to get the next even number you add 2
So it's X+ (X+2)+ (X+4)=93
X is the first # X+2 is the next # X+4 is the 3rd number if you want to check add the numbers to make sure they add up to 93
The smallest of course is X
Answer:
60 feet
Step-by-step explanation:
a - 2x
b - x
c - 3x
120/6 = 20
20 x 3 = 60
