Answer:

<h3>11</h3>

Step-by-step explanation:

The sum of interior angles is equal to exterior angle

Given the following

Interior angles = 5x + 10 and 58

Exterior angle 11x+2

According to the postulate:

5x + 10 + 58 = 11x + 2

5x + 68 = 11x + 2

Collect like terms

5x -11x = 2 - 68

-6x = -66

x = -66/-6

<em>x = 11</em>

<em>The value of x is 11</em>

<em></em>

Over [174]
<h3>Answer: Not direct variation</h3>

The reason why is because it can't be written in the form y = kx

If we solved the given equation for y, we get y = -x+6. It has a y intercept of 6, but it should be zero if we wanted a direct variation equation.
