Answer:
x° =121°
Step-by-step explanation:
The inside angles of a triangle together must equal 180°. Therefore, 58° + 63° + n° = 180° if n equals the third angle inside the triangle. So,
180°-(58°+63°)=n°
180° - 121° = n°
59° = n°
Since the outside angle x and 59° must also equal 180°,
180° - 59° = x°
121° = x°
You can also find the exterior angle without finding the interior by adding the two other interior angles together.
58°+63°=x°
121°=x°

Answer:
The point of intersection of the lines is 
.
Thus, Ariyonne's claim is incorrect.
Step-by-step explanation:
Given equations:
1) 
2) 
To find the point of intersection, we need to solve the given system of equations.
In order to solve the system we will use substitution method.
We will substitute value of 
from first equation in the second equation and solve for 
So, we have
Multiplying both sides by 2 to remove fraction.
Using distribution.
Subtracting both sides by
Adding 4 to both sides.
Dividing both sides by 7.
We can find value of by plugging in in the first equation.
So, the point of intersection of the lines is .
Thus, Ariyonne's claim is incorrect.

Answer:
x = 7
Step-by-step explanation:
The sum of angle measures in a quadrilateral is 360°.
(8x-5)° +107° +83° +119° = 360°
8x = 56 . . . . . . . divide by °, subtract 304
x = 7 . . . . . . . . . . divide by 8
