Given:

In triangle ABC,  a = 6, c = 4, and B = 75°.

To find:

The measure of b.

Solution:

According to the Law of Cosine:

b^2=a^2+c^2-2ac\cos B

Substituting the given values in the above formula, we get

b^2=(6)^2+(4)^2-2(6)(4)\cos (75^\circ)

b^2=36+16-48(0.2588)

b^2=52-12.4224

b^2=39.5776

Taking square root on both sides, we get

b=\sqrt{39.5776}

b=6.291073

b\approx 6.29

The measure of side b is 6.29 units.

Therefore, the correct option is B.

Drag a reason to each box to complete the proof.<br> Please help <br> will give you brainliest
Helga [31]

Answer:

The required proof is shown below.

Step-by-step explanation:

Consider the provided figure.

It is given that KM=LN

We need to prove KL=MN

Now consider the provided statement.

KM = LN                     Given

KM = KL+LM              Segment addition postulate

LN = LM+MN             Segment addition postulate

KL+LM = LM+MN      Substitution property of equality

KL = MN                    Subtraction property of equality

The required proof is shown above.

I need help with letter B, please!
Gala2k [10]

So if you want to fit the y-intercepts or "b", on the y-axis you should go by 25's [0, 25, 50, 75, 100...]

If the x-axis <u>does not have to</u> follow the same pattern (25's), you should go by 5's  [0, 5, 10, 15, 20...]

y = 7x + 50

y = 2x + 175

First I would plot the y-intercepts for each equation, then plot a few points with x = 5, 10, 15      Then draw a straight line.

The point where the two lines meet/cross paths is your solution. It should be (25, 225)  The x-axis is the number of miles, and the y-axis is the total cost. So Truck driver A and B would arrive/be at the same place/meet in 25 miles at the same cost of $225
