Answer: B 163 degrees
Step-by-step explanation:
That's an obtuse angle, bigger than 90 degrees, so we read the appropriate upper scale for the angle.
Answer:
B and E 2020
Step-by-step explanation:
Answer:
1/5 is not greater than 2/7 because 1/5 = 7/35 and 2/7 = 10/35.
-3x + 7y = -16 . . . (1)
-9x + 5y = 16 . . . .(2)
(1) x 3 => -9x + 21y = -48 . . . (3)
(2) - (3) => -16y = 64 . . . (4)
Required equivalent system of equations is
-9x + 5y = 16
-16y = 64
Vertical angles, because the definition of vertical lines is each of the pairs of opposite angles made by two intersecting lines.
