What’s the value of <br> tan (3arc cos 3/4)
Volgvan
<h2>Answer: -1.469</h2>

This trigonometric function can be written as:

tan (3 cos^{-1} (\frac{3}{4}))   (1)

Firstly, we have to solve the inner parenthesis:

cos^{-1} (\frac{3}{4})= 41.409   (2)

Substituting (2) in (1):

tan (3(41.409))=tan(124.228)   (4)

Finally we obtain the value:

tan(124.228)=-1.469

If b is the midpoint of ac, ab=12x+11 and bc= 14x - 1, find AB
xxMikexx [17]

Answer:

AB = 83

Step-by-step explanation:

The mid-point of any segment divides the segment into two equal parts

∵ B is the midpoint of segment AC

→ That means B divides AC into two equal segments AB and BC

∴ AB = BC

∵ AB = 12x + 11

∵ BC = 14x - 1

→ Equate them

∴ 14x - 1 = 12x + 11

→ Subtract 12x from both sides

∵ 14x - 12x - 1 = 12x - 12x + 11

∴ 2x - 1 = 11

→ Add 1 to both sides

∵ 2x - 1 + 1 = 11 + 1

∴ 2x = 12

→ Divide both sides by 2

∵ \frac{2x}{2}=\frac{12}{2}

∴ x = 6

→ To find AB substitute x by 6 in its expression

∵ ab = 12x + 11

∵ x = 6

∴ AB = 12(6) + 11

∴ AB = 72 + 11

∴ AB = 83
