<u>Answer:</u>
- <u>x = 33</u>
- <u>Indicated angles: 126</u>°
<u>Step-by-step explanation:</u>
We can tell that 4x - 6 is equal to 2x + 60 because they are vertically opposite angles. Now, let's solve.
- => 4x - 6 = 2x + 60
- => 4x - 2x = 6 + 60
- => 2x = 66
- => x = 33
Since we have found the required variable, we can now solve the indicated variables.
Given angles:
Let's solve 4(33) - 6 first.
Therefore, 4(33) - 6 measures about 126°. Now, let's solve 2(33) + 60.
We can clearly see that both angles are equal (126 = 126) Because of vertically opposite angles.
<u>Conclusion: </u>
Therefore, the required variable is 'x = 33' and when we substitute the variable in both angles, we find that both angles show 126°.
Hoped this helped.

Step-by-step explanation:
Simplifying 40 = 15 + -9x + -2
Reorder the terms: 40 = 15 + -2 + -9x
Combine like terms: 15 + -2 = 13 40 = 13 + -9x
Solving 40 = 13 + -9x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '9x' to each side of the equation. 40 + 9x = 13 + -9x + 9x
Combine like terms: -9x + 9x = 0 40 + 9x = 13 + 0 40 + 9x = 13
Add '-40' to each side of the equation. 40 + -40 + 9x = 13 + -40
Combine like terms: 40 + -40 = 0 0 + 9x = 13 + -40 9x = 13 + -40
Combine like terms: 13 + -40 = -27 9x = -27
Divide each side by '9'. x = -3
Simplifying x = -3
