angle sum theory
A) 3
B) 19
C) 12
D) 10

Answer:
[tex]\huge\boxed{C)\ 12}[/tex]
Step-by-step explanation:
The three interior angles in a triangle will always add up to 180°.
Therefore
[tex]59+(6x-10)+59=180\\(59+59-10)+6x=180\\108+6x=180\qquad|\text{subtract 108 from both sides}\\10-10+6x=180-108\\6x=72\qquad|\text{divide both sides by 6}\\\dfrac{6x}{6}=\dfrac{72}{6}\\\boxed{x=12}[/tex]
Answer:
Option C
The value of x is 12°
Step-by-step explanation:
Here, we know that in a Triangle The sum of all three angles is 180°.
Now,
59° + 59 + (6x - 10)° = 180°
118° + 6x - 10° = 180°
6x + 108° = 180°
6x = 180° - 108°
6x = 72°
x = 72° ÷ 6
x = 12°
Thus, The value of x is 12°
