Answer:
Option C is the correct answer.
Step-by-step explanation:
The original painting dimensions are = 92 cm long by 73 cm high
The first poster measures 120 cm long by 100 cm high.
Lets check the ratio.
by
This reduces to nowhere.
The second poster measures 138 cm long by 109.5 cm high.
Ratio is : by
This reduces to 1.5 by 1.5
Therefore we can say - The first poster is not an accurate representation of the painting, but the second poster is an accurate representation.
The ratio defines it all. The ratio of the first poster to original picture is not accurate but the ratio of second one is accurate.

Answer:
a. When vector is added to vector , the resultant is vector such that its magnitude and direction is proportional to the resultant magnitude and direction of the component vectors.
b. ∅ = (Rx/Ry)
Step-by-step explanation:
Vectors are used to express physical quantities with magnitude and direction. Vectors can be added by the parallelogram method or the triangular method of addition. the magnitude and direction of the resultant vector is usually proportional to the magnitude and direction of the component vectors.
The direction of the angle is found as
tan∅ = Rx/Ry
∅ = (Rx/Ry)
