Answer:
x = 4
Step-by-step explanation:
The ratio of the side opposite the large filled dot to the hypotenuse is ...
16/20 = x/5
(4/5)(5) = x = 4 . . . . multiply by 5
The value of x is 4.

The angle marks tell us the triangles are similar.
Answer:
(-1,-5)
Step-by-step explanation:
So we have the system:
y=3x-2
x-y=4.
We are asked to use substitution. Luckily, it is already setup for this because one of the equations has one of the variables solved for, namely the y=3x-2 equation. We are going to insert y=3x-2 into x-y=4 and solve for x.
x-y=4 (with y=(3x-2) ):
x-(3x-2)=4
Distribute:
x-3x+2=4
Combine like terms:
-2x+2=4
Subtract 2 on both sides:
-2x =2
Divide both sides by -2:
x =-1
Now if y=3x-2 and x=-1, then y=3(-1)-2=-3-2=-5.
So the solution is (-1,-5).

Answer:
30ft
Step-by-step explanation:
The hypotenuse is the distance from home to second, or side x.
The legs are from home to first and from first to second.
