Answer:

Part 1) It is not possible to apply the Pythagorean Theorem to find the missing side, because is not a right triangle

Part 2) I would use the law of the cosine, because to apply the law of sine I would need to know the value of angle C or angle B

Part 3) The length of side CB is $369\ units$

Part 4) The measure of angle C is $35\°$

Part 5) The measure of angle B is $88\°$

Step-by-step explanation:

Part 1) Can you use Pythagorean Theorem to find the missing side?

we know that

The Pythagorean Theorem is used in a right triangle

The triangle ABC of the figure is not a right triangle

therefore

It is not possible to apply the Pythagorean Theorem to find the missing side

Part 2) Would you use Law of Sine or Law of Cosine to find the length of side CB?

I would use the law of the cosine, because to apply the law of sine I would need to know the value of angle C or angle B

Part 3) Find the length of side CB. Show your work and round your answer to the nearest whole number

Applying the law of cosine

$BC^{2}=AB^{2}+AC^{2}-2(AB)(AC)cos(A)$

substitute the values

$BC^{2}=255^{2}+440^{2}-2(255)(440)cos(57\°)$

$BC^{2}=136,408$

$BC=369\ units$

Part 4) Find the measure of angle C. (Hint: use the other “Law”). Round your answer to the nearest whole degree

Applying the law of sines

$\frac{AB}{sin(C)}=\frac{CB}{sin(A)}$

substitute the values

$\frac{255}{sin(C)}=\frac{369}{sin(57\°)}$

$sin(C)=255*sin(57\°)/369=0.5796$

$C=arcsin(0.5796)=35\°$

Part 5) What is the measure of angle B? Show your work and round your answer to the nearest whole degree.

Remember that

the sum of the interior angles of a triangle must be equal to 180 degrees

substitute the values and solve for <B

$57\°+$

-5 3/8 -2 11/12 in simplest form

Tpy6a [65]

Conversion a mixed number 5 3

to a improper fraction: 5 3/8 = 5 3

= 5 · 8 + 3

= 40 + 3

= 43

To find new numerator:

a) Multiply the whole number 5 by the denominator 8. Whole number 5 equally 5 * 8

= 40

b) Add the answer from previous step 40 to the numerator 3. New numerator is 40 + 3 = 43

c) Write previous answer (new numerator 43) over the denominator 8.

Five and three eighths is forty-three eighths

Conversion a mixed number 2 11

to a improper fraction: 2 11/12 = 2 11

= 2 · 12 + 11

= 24 + 11

= 35

To find new numerator:

a) Multiply the whole number 2 by the denominator 12. Whole number 2 equally 2 * 12

= 24

b) Add the answer from previous step 24 to the numerator 11. New numerator is 24 + 11 = 35

c) Write previous answer (new numerator 35) over the denominator 12.

Two and eleven twelfths is thirty-five twelfths

Subtract: 43

- 35

= 43 · 3

8 · 3

- 35 · 2

12 · 2

= 129

- 70

= 129 - 70

= 59

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(8, 12) = 24. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 12 = 96. In the next intermediate step the fraction result cannot be further simplified by cancelling.

In words - forty-three eighths minus thirty-five twelfths = fifty-nine twenty-fourths.
