Math Problem Statement

Find the values of x and y given the following angles: (18y + 5)°, (10x - 61)°, and (x + 10)°.

Solution

The image you provided shows a geometry problem where you are asked to find the values of xx and yy. The angles are labeled as follows:

  • (18y+5)(18y + 5)^\circ
  • (10x61)(10x - 61)^\circ
  • (x+10)(x + 10)^\circ

It appears to be a set of vertically opposite angles or angles on a straight line.

Let's break down the relationships:

  1. The two angles (18y+5)(18y + 5)^\circ and (10x61)(10x - 61)^\circ are vertically opposite angles, meaning they are equal: 18y+5=10x6118y + 5 = 10x - 61

  2. The angles (10x61)(10x - 61)^\circ and (x+10)(x + 10)^\circ are adjacent and together form a straight line, which means they are supplementary. Therefore: (10x61)+(x+10)=180(10x - 61) + (x + 10) = 180^\circ

We now have two equations:

  1. 18y+5=10x6118y + 5 = 10x - 61
  2. (10x61)+(x+10)=180(10x - 61) + (x + 10) = 180

Let me solve these equations for xx and yy.The solution to the system of equations is:

  • x=21x = 21
  • y=8y = 8

Would you like a more detailed explanation of how these were solved, or do you have any further questions?

Here are some related questions to expand your understanding:

  1. What are vertically opposite angles, and why are they always equal?
  2. Why do adjacent angles on a straight line sum up to 180180^\circ?
  3. Can these concepts of angles apply to polygons, and how?
  4. How would the process change if the problem involved more than two unknowns?
  5. What if the angles formed a triangle instead—how would you solve for the unknowns?

Tip: When solving geometry problems involving angles, always look for relationships like vertically opposite, supplementary, or complementary angles to set up equations.
