Answer:
<em>x = 12</em>
Solve for x:
<em>Using Pythagorean Theorem </em>
a^2 + b^2 = c^2
a = 9
c = 15
b = x
9^2 + x^2 = 15^2
81 + x^2 = 225
x^2 = 144 | sqrt
x = 12
2 Answers: A) line symmetry and B) rotational symmetry
=====================================================
Explanation:
We have line symmetry because we can draw a vertical line down the center, and this is a mirror line. One half folds over the vertical line to match up with the other half. There are other lines of symmetry as well.
We also have rotational symmetry because we can rotate the figure some amount of degrees and have it line up with its original image. The before and after will be identical. This applies to any regular polygon.
Answer:
B negative
Step-by-step explanation:
use real numbers?
n is +9
m is -11
m/n * (-m*n^2)
-11/9 * (11*81)
-11/1 * (11*9)
-11 * 99
-1089
