Answer:
length=52mm
Step-by-step explanation:
For an equilateral triangle A=B=C=x
perimeter= A+B+C
156=x+x+x
3x=156
x=52mm
Answer:
Nico, Raj and Sandra are correct
Step-by-step explanation:
we have
<em>Method 1</em>
Solve for x
That means ----> isolate the variable x
we have
Multiply by 5/2 both sides
subtract 6 both sides
<em>Method 2</em>
Solve for x
That means ----> isolate the variable x
we have
Multiply by 1/2 both sides
Multiply by 5 both sides
subtract 6 both sides
<em>Method 3</em>
Solve for x
That means ----> isolate the variable x
we have
Apply distributive property left side
subtract 2 both sides
Multiply by 5/2 both sides
therefore
Nico, Raj and Sandra are correct
Answer:
In 5:
UM and MS are equal since the diagonals US and VT have perpendicularly bisected each other.
So,15=6x-3
15+3=6x
18=6x
3=x
In 6:
ET=TC
8=x-4
8+4=x
12=x
Area = base x height /2
Base =26.5
Height =40
26.5 x 40 /2 = 530
