Supplementary Angles:
Supplementary angles are two angles that add up to 180 degrees. In other words, if the sum of two angles is 180 degrees, then they are supplementary.
Given:
The two angles are (30-a) and (125-2a). We need to find the value of 'a' if these angles are supplementary.
Setting up the Equation:
To find the value of 'a', we'll set up an equation using the given information.
The sum of the two angles is equal to 180 degrees, so we have:
(30-a) + (125-2a) = 180
Now, let's solve this equation step by step.
Solving the Equation:
Step 1:
Combine like terms on the left side of the equation.
30 - a + 125 - 2a = 180
155 - 3a = 180
Step 2:
Move the constant term to the right side of the equation.
-3a = 180 - 155
-3a = 25
Step 3:
Divide both sides of the equation by -3 to solve for 'a'.
a = 25 / -3
a ≈ -8.33
Interpreting the Result:
The value of 'a' is approximately -8.33.
Conclusion:
Given that the two angles are (30-a) and (125-2a), if they are supplementary, the value of 'a' is approximately -8.33.
