Answer:
A) 1 line of symmetry
Step-by-step explanation:

<u>√3</u>
x is the length of the third side
x²+1² = 2² { Pythagorean Theorem}
x²+1 = 4 {Simplify}
x²=3 {Subtract 1 from each side}
x=√3 {Take the square root of each side}
The Length of the third side is √3

Answer:
x = -10/3
Step-by-step explanation:
2/3x + 2/3 + 1/5x = 2/3x
Subtract 2/3x from each side
2/3x-2/3x + 2/3 + 1/5x = 2/3x-2/3x
2/3 + 1/5x = 0
Subtract 2/3 from each side
2/3 -2/3+ 1/5x =0- 2/3
1/5x = -2/3
Multiply each side by 5
5*1/5x = 5*-2/3
x = -10/3
