Answers:
x = 57
y = 86
z = 37
=================================================
Work Shown:
x+123 = 180 .... since x and 123 form a straight line
x = 180-123
x = 57
y = 86 since the y and 86 angles are vertical angles
-------
For any triangle, the three angles always add to 180. So,
x+y+z = 180
57+86+z = 180
143+z = 180
z = 180-143
z = 37
As a check,
x+y+z = 57+86+37 = 180
which confirms the value of z

The value of xis
o, and the value of yis
Answer:
x = 60°
y = 50°
Step-by-step explanation:
✅x = 180° - (50° + 70°) (sum of interior angles of a triangle theorem)
x = 180° - 120°
x = 60°
✅Based on the exterior angle theorem, the sum of the opposite interior angles of a triangle = the exterior angle.
Therefore,
50° + 60° = x + y
Plug in the value of x
50° + 60° = 60° + y
110° = 60° + y
y = 110° - 60°
y = 50°
Answer:
$56
Step-by-step explanation:
Multiply to find how much he took out.
18 * 8 = 144
Subtract to find how much he has left.
200 - 144 = 56

Answer:
Step-by-step explanation:
Which system of equations has infinitely many solutions?
4 x + 2 y = 5 // -4x - 2y = 1
-10x + y = 4 // 10x - y = -4.
-8x + y = 2 // 8x-y = 0.
-x + 2 y = 6 // 7x-2y = 12.
It's important to know that a linear system of equations has infinitely many solutions when both equations represents the same line, that means one line is on top of the other one, that's why the shared infinite points.
In this case, notice that if we compare the second system, you would find that both equations are the same,
If we multiply the first equation by -1
Which means the system has infinitely many solutions, because both equations represent the same line, so the shared all possibles points.
Therefore, the right answer is the second choice.
