Answer:
A:the polynomial is a trinomial
A line is 180° so if you are given 43°on part of line l
180-43=137
So x=137°
Answer:
2x+2y=310
x-y=55
multiply seond equation by 2 and adding to first equation
2x-2y=110
add
2x-2y=110
2x+2y=310 +
4x+0y=420
4x=420
divide 4
x=105
sub
x-y=55
105-y=55
minuse 105
-y=-50
mult -1
y=50
the numbers are 105 and 50
