To help you with the problem, I need to know more details about the figure and the angles involved. However, I can guide you through the steps to handle similar problems.
(a) To write an equation, you'll typically need information about the relationship between the angles. For example, if you have two angles \( A \) and \( B \) that are supplementary (which means they add up to \( 180^\circ \)), the equation would be:
\[ A + B = 180^\circ \]
Alternatively, if the angles are complementary (adding up to \( 90^\circ \)), you would write:
\[ A + B = 90^\circ \]
If the angles are equal, you might write:
\[ A = B \]
Make sure to include any specific angle measurements provided in the figure you have.
(b) Once you have established the equation, you can solve for the unknown angle(s). Depending on the equation you wrote, you might isolate the variable and calculate the measure of each angle.
For example, if you found that:
\[ A + B = 180^\circ \]
and you know \( A = 45^\circ \):
\[ 45^\circ + B = 180^\circ \] \[ B = 180^\circ - 45^\circ = 135^\circ \]
This method applies to finding the degree measure of each angle.
If you have specific angles or relationships in your question, feel free to share them so that I can provide a more tailored response!
