Answer:
8
Step-by-step explanation:
∠1 = (6x + 2)° (vertically opposite angles are equal)
15x + 10° +∠1 = 180° (co-interior angles are equal)
15x + 10° + 6x + 2° = 180°
15x + 6x + 10° + 2° = 180°
21x + 12° = 180°
21x = 180° - 12°
21x = 168°
x = 168/21
x = 8
hope u understood!

The local hamburger shop sold 115 hamburgers and 345 cheeseburgers on Friday.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let x represent the number of hamburger sold and y represent the number of cheeseburgers sold, hence:
x + y = 460 (1)
Also:
y = 3x (2)
From both equations:
x = 115, y = 345
