Sent a pic of the solution (s). When it asked to factor out the coefficient of the variable just divide both numbers by the coefficient, and present it on the outside like I showed you.
Check the picture below.
for "b", well, recall that the sum of all interior angles in a triangle is 180°.
for "a", "c" and "d", well, all those are just <u>intercepted arcs</u>.

Hope this helps!
