it represents that the angle forms at the vertex E
Answer:
46.6
Step-by-step explanation:
have a good day
34.9 because its 90 angle so you subtract the 55.1
I: 2x+y=5
II:3x+2y=4
start by eliminating y
-2*I: -4x-2y=-10
II: 3x+2y=4
add both equations together
-2*I+II: -4x-2y+3x+2y=-10+4
-1x=-6
x=6
insert x=6 into I:
2*6+y=5
y=5-12
y=-7
so the solution is x=6, y=-7
