Answer: x=120°
Step-by-step explanation:
What you are looking for is the value of the exterior angle of the regular polygon.
For a n-sided regular polygon, the external angle is given by the formula 360°/n.
Because the shape in this example is a regular triangle, the value of n is 3.
360°/n
=360°/3
=120°
Therefore, x=120°
Answer:
x=7/3
Step-by-step explanation:
3(x-4)=-5
3x-12=-5
3x=7
x=7/3
