It’s isosceles because 2 acute angles and one 90 degree angle makes an isosceles triangle
Answer:

Step-by-step explanation:
*Move terms to the left and set equal to zero:
4㏒(√x) - ㏒(3x) - ㏒(x²) = 0
*simplify each term:
㏒(x²) - ㏒(3x) - ㏒(x²)
㏒(x²÷x²) -㏒(3x)
㏒(x²÷x² / 3x)
*cancel common factor x²:
㏒(
)
*rewrite to solve for x :
10⁰ = 
1 = 
1 · x =
· x
1x = 
*that would be our answer, however, the convention is to exclude the "1" in front of variables so we are left with:
x = 
The correct answer is
y=2x-9
Since the lines are parallel, they will gave the same slope (in this case it’s 2)
Our equation will be
y=mx+b
We know the slope is 2, and they’ve given us x and y coordinates. Plugging it in to the slope equation we get
1=2(5)+b
1=10+b
Subtract 10 from both sides and you get
-9=b
Putting it together our new parallel line will be
y = 2x - 9
