Hey there!

The answer to your question is a = s - b - C/2

<u>To solve for "a", we must get "a" on it's own side of the equal sign.</u> We can first subtract "s" from both sides:

<em>0 = a + b + C/2 - s</em>

Then, we can subtract a from both sides:

<em>-a = b + C/2 - s</em>

Finally, we divide both sides by -1, so a is by itself.

<em>a = -b - C/2 + s</em>

And we can rearrange it to the standard form:

a = s - b - C/2

Good luck, and hope it helped! Have a great day!

I'm not sure about what exactly your teacher is looking for, but the actual congruency conjecture you would use is:

(angle symbol) 1 (congruency symbol) (angle symbol) 8 - Because they are alternate exterior angles
