In the given figure,
Angle 108° + 12x = 180°
because they for pair of co- interior angles which are supplementary.
so,
hence , value of x = 6°
Variables can be used to represent unknown numbers in a equation or expression that you will later find out what they are
Answer:
78.5398 cm^2
Step-by-step explanation:
r = 1/2*d => d = 10 cm
r = 5
A = pi*r^2
= pi*5^2 => 3.1415*5^2
=> 78.5398
The next two numbers are 7 & 7.6.
