Is the table proportional?

inysia [295]

No. In order to be proportional, y must change directly with x.

Looking at the first two pieces of data, let's find the ratio between x and y.

2/5 and 3/6. These should be equivalent of the table is proportional.

Use the law of sines to find the length of side c

AnnyKZ [126]

Answer:

B. 44.93

Step-by-step explanation:

The law of sines states
$\frac{a}{sinA} = \frac{b}{sinB} = \frac{c}{sinC}$

where a, b and c are the 3 sides of the triangle and A is the angle opposite side a, B the angle opposite side b and C the angle opposite side c

In this particular problem we have

side a = 44, angle A = 46.7
side c = ? , angle C = 48

So 44/sin(46.7) = c/sin(48) or by multiplying both sides by sin(48)

c = sin(48) * 44/sin(46.7) = 44.92937 which is 44.93 rounded to 2 decimal places
