2/9 + (-1/2)
Simplify, 2/9 - 1/2
Change the denominator on both sides into the LCM of 2 and 9
Therefore, 4/18 - 9/18
The answer is -5/18
Scale factor = 12 ÷ 6 = 2
61 ÷ 2 = 30.5 units
Answer:
x = 16.8
Step-by-step explanation:
To get the value of x, we use Pythagoras’ theorem since what we have is a right angled triangle
Mathematically, we have it that;
the square of the hypotenuse (21) equals the sum of the squares of the two other sides
21^2 = 12.6^2 + x^2
x^2 = 21^2 - 12.6^2
x^2 = 282.24
x = √282.24)
x = 16.8
The formula of the measurement of an exterior angle of a regular polygon is
β = 360°/n
where β = exterior angle and n = number of sides
Therefore,
n = 360°/β = 360°/18° = 20 sides
