2 x 9 - 3 x 5 + 4
In math/s we have the rule called BEDMAS
(a.k.a. BODMAS, BIDMAS, PEDMAS, etc)
Brackets
Exponent
Division
Multiplication
Addition
Subtraction
We go from top to bottom of the list of rules for every math equation. There’s just one exception, addition and subtraction are treated equally, and so when we have an equation with just addition and subtraction, we work left to right
2 x 9 - 3 x 5 + 4
We have no brackets and no exponents, and there’s nothing to divide.
So, we do multiplication
18 - 15 + 4
If you remember, addition and subtraction are treated the same. Therefore, we work left to right.
18 - 15 + 4 = 7
You can type your question into goorgle or a calculator, and you’ll get 7!
The sides of a regular polygon with a known interior angles can be found as follows:
Interior Angle = (n−2) × 180° / n
<h3 /><h3 /><h3>Regular polygon</h3>
A regular polygon is a polygon that have equal sides and equal angles.
A regular polygon has the following angles:
- interior angles
- exterior angles
According to the question, the interior angles are given. To know the number of sides of polygon can be calculated as follows:
Note the interior and the exterior angles add up to 180 degrees.
Therefore,
Interior Angle = 180° − Exterior Angle
Exterior angle = 360°/n
Interior Angle = 180° − 360°/n
n = number of sides
Finally,
- Interior angle = (n−2) × 180° / n
