Answer:
Part 1) The area of the figure is
Part 2) The perimeter of the figure is
Step-by-step explanation:
Part 1) Find the area of the figure
we know that
The area of the figure is equal to the area of three squares
so
Part 2) Find the perimeter of the figure
we know that
The perimeter of the figure is equal to two times the length side of the square, plus the circumference of six semicircles ( or the circumference of three circles)
Remember that
The circumference of a circle is equal to
where
D is the diameter of the circle
In this problem
so
simplify
Answer:
Step-by-step explanation:
1) 4x+ 34 = 90°
4x = 90 - 34
4x = 56
x = 56/4
x = 14°
2) 4x +2 + 2x + 10 = 90°
6x + 12 = 90
6x = 90 - 12
6x = 78
x = 78/6
x = 13

The answer is 71

(Pay attention to the subject you're choosing, this is supposed to be in the Chemistry section, not here in the Mathematics)
On the periodic table, the Magnesium Mg is located in period 3, group 2. So it got 12 electrons.
So to become the cation Mg2+, the Magnesium has lost 2 electrons during it's formation.
So 12-2=10.
So there's 10 electrons in the Cation magnesium Mg2+
Hope this Helps! :)
