Because Angle RST is bisected by ray SU it is then split into two even angles and the resulting two angles will be 40 degrees apiece.
7 . 112
8 . 246
for number 7 , you multiply 8 by 16 to get 128 then subtract both windows so you get 112
for number 8 , you find the area of the rectangle which is 10x26 = 260 then add the triangles area which is 130 and you get 390 then subtract the 16 window and 128 door
Multiply the top equation by -3 and added to the second one.
By Elimination.
