120 degrees is anwser because 180-60 is 120 you know the angles of triangle are 60 because it is an equateral triangle
Okay uh
x = 2y + 9
14x + 2y = - 54
14x + 2y = - 54
14(2y + 9) + 2y = - 54
28y + 126 + 2y = -54
30y + 126 = -54
- 126 -126
30y = -180
30y/30 = -180/30
y = -6
x = 2y + 9
x = 2(-6) + 9
x = -12 + 9
x = -3
(x, y) = (-3, -6)
9.79 x 10^5 in standard notation is 979,000.
