O_o Whhhhaaaaat?? How does that make sense.
not clear way ..... clear it
All angles of a triangle *always* equal to 180*. R=120 and two angles on a flat line also equal to 180. So, *180-120=60*. So *60+60+60*, all the angles of the triangle, equals to 180. So angle x=60.
Answer:
7000
Step-by-step explanation:
10^3=1000
1000*7=7000
-4x + 9y = 9...............(1)
x - 3y = -6 Multiply through by 3:-
3x - 9y = -18..............(2)
adding equations (1) and (3):-
-x = -9
x = 9
Substitute for x in equation (1)
-4(9) + 9y = 9
-36 + 9y = 9
9y = 45
y = 5
Answer is x = 9 and y = 5
