Sergeeva-Olga [200]

a = 6.2

Solution:

Given ABC is triangle.

AC = b = 8, BA = c = 11, ∠A = 32.2°

BC = a

To find the length of a:

Law of cosines:

a^{2}=b^{2}+c^{2}-2 b c \cdot \cos A

a^{2}=8^2+11^{2}-2 \times 8 \times 11 \cdot \cos 32.2^\circ

a^{2}=64+121-174 \cdot \cos 32.2^\circ

a^{2}=185-174 (0.8461)

a^{2}=185-147.221

a^{2}=37.779

Taking square root on both sides of the equation.

a = 6.1464

a = 6.2

The length of BC is 6.2.

NARA [144]

Answer:

The distance traveled at a constant speed is directly proportional to the time of travel. If Olivia traveled 112 miles in 3.5 hours, how many miles will Olivia travel in 8.9 hours at the same constant speed?

-----------------

Proportion:

x/8.9 = 112/3.5

---

x = 8.9(112/3.5)

x = 284.8 miles
