Answer:
113.1
Step-by-step explanation:
formula for circle is pie X radius^2
A^2 + B^2 = c^2
12^2 + b^2 = 20^2
144 + b^2 = 400
-144 -144
b^2 = 256
sqrt(b^2) = sqrt(256)
b=16
x=16
You’re using the Pythagorean theorem to solve for this where (a) represents a side of triangle, (b) represents another side and (c) represents the hypotenuse.
Answer:
7n + 14 and 7(n + 2)
Step-by-step explanation:
We know that since our triangle is isosceles, then two of the sides are the same. Given in the problem, we know that these two congruent sides are both 2n + 7. We also know the third side is 3n.
Perimeter is essentially just the sum of the side lengths of the figure. We simply need to add 2n + 7, 2n + 7, and 3n together:
P = 2n + 7 + 2n + 7 + 3n
Combine like terms:
2n + 2n + 3n + 7 + 7
7n + 14
That's one way we can write it. Another way is to factor out the 7:
7n + 14 = 7(7n/7 + 14/7) = 7(n + 2)
Thus, our two expressions are: 7n + 14 and 7(n + 2).
