Answer:
width = 7, length = 11
Step-by-step explanation:
area = 77
length = 3w - 10
width = w
w(3w - 10) = 77
3w^2 - 10w - 77 = 0
(3w + 11)(w - 7) = 0
we rule out 3w + 11 = 0 because w would be negative
so we use w - 7 = 0
so the width = 7
length = 3w - 10
length = 21 - 10
length = 11
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°)
