Answer:
83.5 degrees
Step-by-step explanation:
first, find x:
x+5x-13+4x=180
10x=193
x=19.3
Then, substitute that value for c:
5*19.3-13
=83.5 degrees
You would need too do 5*5=25 if you did 5*7=35 that would be wrong

Step 3. Multiply 12x to both sides of the equation to get rid of the denominators.
Step 4. Subtract 25x to put the equation in quadratic form
