180=interior angle of triangle so
angle TRS IS 180-9X as it is (angles on a straight line)
then angle RTS=5x
and angle TSR=9+x
180=180-9x+5x+9+x
180=-3x+189
180-189=-3x
-9=-3x
x=-9/-3
x=3
How many square feet of the entrance way floor consists of white tiles?

Stack them on top of each other and find the common denominator then multiply to total the denominator. Ex. 1/4 denominator is 8. 4x2 is 8. So 1 times what equals 8. 1! Then you should a new fraction 8/8 which is equivalent to 1.
