Answer:
x=1.85531914
Step-by-step explanation:
Answer:
x=3
Step-by-step explanation:
All the angles added together must equal 360 degrees.
74+43+50+37+12x+12x+11x+17x = 360
Simplify the equation by adding like numbers.
204+52x=360
Subtract 204 from both sides of the equation.
204+52x-204=360-204
52x=156
Now, divide both sides by 52.
52x/52=156/52
x=3

The answer is 3 x 10^12
The figure has reflective symmetry about a line if that line divides the figure in two similar parts, which are reflections of one another.
Notice that the two figures formed when the shape is divided by line k are not similar, since one has 7 vertices and the other just 4.
Notice that the two figures formed when the shape is divided by line m are not similar, since one has 7 vertices and the other just 4.
The line l divides the figure in two shape, one is a trapezoid and the other isn't.
Only line n divides the figure in two similar shapes.
Therefore, the correct choice is B) n only.
Answer:
600
Step-by-step explanation:
Given,
Numbers are 825 and 213.
If the number are equal or greater than 50 then one number will be rounded up. if the number is less then it will rounded down.
Like in this case 25 and 13 are less than 50 so, they will not rounded up.
825 will be rounded to 800.
213 will be rounded to 200.
Subtraction of number
= 800 - 200 = 600
