Step-by-step explanation:
Answer:
40
Step-by-step explanation:
If you look at the ratios you can see the pattern of the first number being multiplied by 4 everytime. Therefore you must multiply 10 by 4.
Lets write the information as an equation, and name x the number unknown:
(x + 4)^2 = 36
that is:
the sum of a number and 4: (x + 4)
then, the square of <span>the sum of a number and 4: (x + 4)^2
so we have:
</span>(x + 4)^2<span> = 36
</span>to solve we calculate square root to both sides of the equation:
(x + 4)<span> = 6
</span>then we solve for x:
x = 6 - 4
x = 2
so the unknown number is 2
The vertices are on the circle
that means that the length should be the radius
