Answer:

BC ≈ 12.6 m

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan31° = \frac{opposite}{adjacent} = \frac{AB}{BC} = \frac{7.6}{BC} ( multiply both sides by BC )

BC × tan31° = 7.6 ( divide both sides by tan31° )

BC = \frac{7.6}{tan31} ≈ 12.6 m ( to 3 sf )

Please add this problem 4 5/6 + 6/7=
sweet [91]
Convert to a mixed number:
239/42

Divide 239 by 42:
4 | 2 | 2 | 3 | 9

42 goes into 239 at most 5 times:
 | | | | 5
4 | 2 | 2 | 3 | 9
 | - | 2 | 1 | 0
 | | | 2 | 9

Read off the results. The quotient is the number at the top and the remainder is the number at the bottom:
 | | | | 5 | (quotient)
4 | 2 | 2 | 3 | 9 | 
 | - | 2 | 1 | 0 | 
 | | | 2 | 9 | (remainder)


The quotient of 239/42 is 5 with remainder 29, so:

Answer: 5 29/42
