B. c = ((3)sin45°)/sin40°

Side a is given information: 3cm, and we can find angle A (which is the angle opposite side a) by subtracting the other two angles from 180 because the total interior angle measures of a triangle add to equal 180°.

Angle A = 180 - (95+45) = 40°.
This can be substituted into the equation for the law of sines.

sin(40)°/3 = sin(45)°/c
—Cross multiply
c•sin(40)° = 3•sin(45)°
—divide both sides by sin40 to get the variable c alone and we get:
c = (3)sin(45°)/sin(40°)

this also simplifies to 3.3 cm.

How do you answer this question.
Ipatiy [6.2K]
Lets write this out:-

\frac{50}{100} + \frac{30}{100}

To answer this we just need to add the numerators of both fractions because the denominator's are already common multiples. 

\frac{50}{100}+ \frac{30}{100} = \frac{80}{100}

Now lets simplify \frac{80}{100}.

\frac{80/20}{100/20}=  \frac{4}{5}

So, \frac{50}{100}+  \frac{30}{100} = \frac{80}{100}= \frac{4}{5}

Hope I helped ya!! xD

PIT_PIT [208]

Answer:

4 hours

Step-by-step explanation:

Since the initial fee is $90, you will subtract $90 from $330, getting $240. Since every hour after 1 hour is $60, you would divide $240 by $60 getting 4 hours
