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.

Find the quotient<br>9) 4,878​
guajiro [1.7K]

Answer: 542

Step-by-step explanation:

The quotient is known as the final answer gotten after the value of 4878 has been divided using 9. The answer as such will be 542 (i.e 4878/9)

9 goes in 48 five times, 5 is written and remainder of 3 is kept above 7 to make it 37; then 9 goes in 37 four times, 4 is written and the reminder of 1 is written above 8 to make it 18; and finally 9 goes in 18 two times without remainder, then we write 2. Combining the answers gives our Final answer 542.
