The angles below are supplementary. What is the value of x?

Step-by-step explanation:

In order to solve this equation, we need to know that both values add up to make a supplementary angle, or a 180° angle. Therefore, adding the values and setting them equal to 180 will solve for x.

   Add like terms to simplify the equation.

    Subtract 103 from both sides of the equation.

    Divide by 7 on both sides of the equation to isolate the variable.

11°

Step-by-step explanation:

Since (7x + 33°) and 70° are supplementary angles.

Hence,

7x + 33° + 70° = 180°

7x + 103° = 180°

7x = 180° - 103°

7x = 77°

x = 77°/7

x = 11°

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
