Since the triangles are similar then the ratios of corresponding sides are equal, that is
= 
( substitute in values )
= 
( cross- multiply )
12(x - 1) = 72 ( divide both sides by 12 )
x - 1 = 6 ( add 1 to both sides )
x = 7

The parallel line segment SV is half of RW
that is x = 7.5
SV also divides the sides RT and WT in proportion, that is
= 
( cross- multiply )
10y = 24 ( divide both sides by 10 )
y = 2.4
The answer is A because if u shift 4 units up then it's +4
The new value after the original value is increased by 30% is 1.3 times the original value.

Percentage</h3>
Percentage is used to express a fraction number or decimal in fraction of hundred. It is given by:
Percentage = [(new value - original value) / original value] * 100%
Let x represent the new value and y represent the original value, hence:
30% = [(x - y)/y] * 100%
0.3 = (x - y)/y
x - y = 0.3y
x = 1.3y
The new value after the original value is increased by 30% is 1.3 times the original value.
