Answer:
50°, 130°
Step-by-step explanation:
All measures are in degrees. Let x represent "one angle". Then the other is (180-x) and we can write the relation ...
3x = 20 +(180 -x)
4x = 200 . . . . . . . add x, collect terms
x = 50 . . . . . . . . . . one angle
180 -50 = 130 . . . .the other angle
The measures of each angle are 50° and 130°.
Answer:
i'm pretty sure it's B
Step-by-step explanation:
Answer:
3 + 5x = 4x - 6
Let's do it quickly and simply,
Let's gather the like terms
5x - 4x = -6 - 3
x = - 9
Hope it helps!
