8. What is the value of x?

x = 8°

Step-by-step explanation:

Given the three angles with measurements, m < 90°, m < 40°, and m < (6x + 2)°, in which the sum of their measurements equal 180°,

We can establish the following formula to solve for the value of x:

180° = m < 90° + m < 40° + m < (6x + 2)°

180° = 90° +  40° + 6x + 2

180° = 132° + 6x

Subtract 132° on both sides of the equation:

180°- 132° = 132° + 6x - 132°

48° = 6x

Divide both sides by 6 to solve for x:

x = 8°

To verify whether this is the correct answer, plug in the value of x into the original equation:

180° = m < 90° + m < 40° + m < (6x + 2)°

180° = 90° +  40° + 6(8)° + 2°

180° = 90° +  40° + 48° + 2°

180° = 180°

Therefore, we derived the correct value for x = 8°.
