What exactly are we solving?? the rest of the angles or the perimeter?
Answer:
Step-by-step explanation:
2x-25,6=90
2x=90+25,6
2x=115,6
x=57,8
for the first one set 3y+y=180 and y+x=180
the second one set w+y=180, 42+x=180, y+20=180, and 87+v
Answer:
x=11
Step-by-step explanation:
(7x+14)=(9x-8)
7x-9x=-14-8
-2x=-22
-2x/-2=-22/-2
x=11
6,4 would be the write answer.
