Answer:
b) 2 7/12 ft
Step-by-step explanation:
The difference is ...
(17 5/12 ft) - (14 5/6 ft) = (17 -14) ft + (5/12 -5/6) ft
= 3 ft + (5/12 -10/12) ft = 3 ft - 5/12 ft
= 2 7/12 ft
(-7)^2 + 4(-7) -5
= 49 - 28 -5
= 16
The triangle is a right triangle with:
1) leg c opposed to angle C.
2) leg b opposed to angle B.
3) hypotenuse, a, opposed to angle A.
So, using the definitions of the trigonometric ratios, you get:
1) sin C = opposite leg / hipotenuse = c / a.
2) tan B = opposite leg / adjacent leg = b / c
=> sin C * tan B = [c / a] * [b / c] = b / a.
<span>Answer: b / a</span>
