Which proportion could be used to find the length of side b?

the answer is the option A

Step-by-step explanation:

Step 1

Find the measure of angle C

we know that

the sum of the internal angles of the triangle is equal to

so

Step 2

Applying the law of sines

substitute the values

A sin23/6.2= sin85/b

Step-by-step explanation:

215.92 dollars is the answer

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
