A) is right
b) just subtract ljm and kjm so 145-48 = 92°
c) 9x-25=7x+7 so here you put npq=mpq+mpn and you combine terms so it's now 2x=32 then divide by 2 on both sides and x= 16
now you just plug it into 3x-5 and you get 43°

Rodney has a board 5/6 yd long. He used 1/5 of the board to make a frame. How long is the board used to make the frame.
Katarina [22]
He uses 1/5 OF 5/6 of a yard. That "of" is very important, because it indicates that, to find the answer, you multiply the two together. 

That being said (1/5) times (5/6) =5/30, which can be reduced to 1/6 yds to make the frame
