Answer:
6
Step-by-step explanation:
Given an isosceles triangle the two sides opposite of congruent angles are equal to eachother, so you can create an equation setting the two sides equal to eachother and solve for x.
The length of AC is simply x, therefore 6
<span>(x+3)^2 = x^2 + 69
x^2 + 6x + 9 = x^2 + 69
x^2 + 6x + 9 - x^2 = x^2 + 69 - x^2
6x + 9 = 69</span>
Answer:
Comp set or a competitive set
Step-by-step explanation:
Answer:
Step-by-step explanation:
7g = x miles
7 grade is x miles
8g = 7g + 15%
8 grad is 15% more than 7 grade
put what 7g is equal to into the 8g equation
8g = x + 15%
Let
x---------> the length of the sides that have the same length in meters
we know that
the perimeter of the figure is equal to
<u>solve for x</u>
therefore
<u>the answer is</u>
Each of the same length side is long
