Answer:
a²+b²=c² so you take 15² =225. then you take 8²=64 then you add 225+64=289. Then you find the √289 That equals 17
C=17

the lines are parallel if a pair of corresponding angles are congruent
Answer : 
Given: axis of symmetry of x = –2
To find axis of symmetry we use formula 
We check which equation has axis of symmetry x= -2
(1) 
a=1 , b=4 so axis of symmetry 
(2) 
a=1 , b=-4 so axis of symmetry 
(3) 
a=1 , b=6 so axis of symmetry 
(4) 
a=-2 , b=-8 so axis of symmetry 
(5) 
a=-2 , b=8 so axis of symmetry 
So
and
has axis of symmetry x=-2
Using the elimination method, the value of x in the system of equations is calculated as: 8.
<h3>How to Solve a System of Equations by Elimination?</h3>
To solve a system of equations given using the elimination method, do the following:
Multiply 2x - 5y = 1 by 2 and multiply -3x + 2y = -18 by 5 to get the following:
4x - 10y = 2 --> eqn. 1
-15x + 10y = -90 --> eqn. 2
Add
-11x = -88
Divide both sides by -11
x = 8
