Answer:
True
Step-by-step explanation:
given -
≥ 10 (multiply both sides by 18 )
- t ≥ 180 ( multiply both sides by - 1)
Remembering to reverse the symbol as a consequence of multiplying by a negative quantity, hence
t ≤ - 180
Answer:
83! :)
Step-by-step explanation:
It all equals 180.
So,
53+44+?=180
180-53-44=83! :)
83+53+44=180! :)
Step-by-step explanation:
We have 6 angles. They are:-
- Accute angle (between 0° and 90°)
- Right angle (exactly 90°)
- Obtuse angle (between 90° and 189°)
- Straight angle (exactly 180°)
- Reflex angle (between 180° and 360°)
- Complete turn (exactly 360°)
