Answer:
Option (2)
Step-by-step explanation:
By applying tangent rule in the given right triangle,
tan(42°) = 
tan(42°) = 
Width = 
Width = 6.67
Therefore, width of the given triangle is 6.67 units.
Option (2) is the correct option.
For this case we have by definition, if "y" varies directly with "x", then it is true that:

Where:
k: It is the constant of proportionality
We have the following equation:

So, as mentioned above we have to:

Answer:

Option B
1)421x=6
x=70
2)x+6(6x)=420
x+36x=420
37x=420
x=11
3)x-6x=420
5x=420
x=84
4)x+6x=420
7x=420
x=60
