The angle sum of a triangle is 180 degrees
So add all the angles inside and equate it to 180: 5x+2x+3x= 180
10x=180
x= 18
Because you’re finding angle L, which is 3x, and we find what the numerical value of x is
Angle L = 3x18 = 54.

Answer:
Step-by-step explanation:
That is not a parallelogram. It has more than four sides.
Area of the white part of the figure is 4×20 = 80 m²
If you expand the figure to include the white part, its area is 9×23 = 207 m².
Green area = 207-80 = 127 m²
Answer:
the roots are n = 1 + √15 and n = 1 - √15
Step-by-step explanation:
In this case I would immediately rewrite n² - 2n - 5 = 10 as
n² - 2n = 10 + 5 = 15.
To complete the square: Identify the coefficient of n (it is -2). Halve that, obtaining -1, square this result, and then add the outcome (1) to and subtract the outcome (1) to n² - 2n:
n² - 2n <em>+ 1 - 1 </em> = 15
Next, rewrite n² - 2n + 1 as the square of a binomial:
(n - 1)² = 15
Finally, take the square root of both sides:
n - 1 = ±√15
so that the roots are n = 1 + √15 and n = 1 - √15
The company paid $2000 for the printer
Step-by-step explanation:
Let x be the price of the printer for which the company bought it.
If x is the price of printer, then 25% of x will be the profit made by the company.
That is:
0.25x
According to the statement,
The cost and profit earned by company are equal to 2500
So,
Dividing both sides by 1.25
Hence,
The company paid $2000 for the printer

Answer:
17/6 or 2 5/6 gallons of paint
Step-by-step explanation:
First, do 17/6= 2 5/6.
That's really all, but I can't help you with the number line because of no attachment, but just put it on the part where it says 17/6 or 2 5/6.
Hope this helped!
