Answer:
12
Step-by-step explanation:
4 and 12 only share 12 which is the lowest number :D
Assuming that the figures given are square such that the scale factor between them is equal to 28/8 which can be further simplified into 7/2. The ratio of the perimeter is also equal to this value, 7/2. However, the ratio of the areas is equal to the square of this value giving us an answer of 49/4.
Step-by-step explanation:
(i)
m <em>L</em><em> </em>BOC = 2× m <em>L</em><em> </em>BAC = 2×56 = 112°
(ii)
m <em>L</em><em> </em>BCA = m <em>L</em><em> </em>BAT = 75°
m <em>L</em><em> </em>OCB = (180°-112°)/2 = 68°/2 = 34°
so, m <em>L</em><em> </em>OCA = 75°-34° = 41°
