Answer:
33°, 57°
Step-by-step explanation:
The sum of angle measures is 90°, so we can write ...
(x +3) + (2x -3) = 90
3x = 90 . . . . . . . . . . . . simplify
x = 30 . . . . . . . . . . . . . divide by 3
The first angle is 30+3 = 33 degrees.
The second angle is 2·30-3 = 57 degrees.
_____
Check:
33° +57° = 90°
-9
Adding a negative 3 is the same as subtracting 3, so if you do -6 - 3 you get -9
It's a Polygon
Answer: it is 2 1/3
answerr:
2 ≤ 2x or 2x ≥ x + 5
x ≤ 1 or x ≥ 2.5
