<em>Note: I am assuming we have to determine the value of the side 'x'.</em>

Answer:

The value of x = 8.1 units

Step-by-step explanation:

<em>Note: I am assuming we have to determine the value of the side 'x'.</em>

Given

Angle Ф = 32°

To determine:

x = ?

Using the trigonometric ratio

tan Ф = opposite / adjacent

here

Ф = 32°

opposite to angle 32° = x

adjacent to angle 32° = 13

Therefore,

substituting adjacent = 13, Ф = 32°, opposite = x in the equation

tan Ф = opposite / adjacent

$\tan \left(32^{\circ \:}\right)=\frac{x}{13}$

$\:x\:=\:13\:\times tan\:32^{\circ }\:$

x = 8.1 units tan 32° = 0.62

Therefore, the value of x = 8.1 units

Your friend tossed a fair coin when you weren’t around. She has a habit of messing with you every once in a while, and so there

zaharov [31]

Answer:

Step-by-step explanation:

Given that your friend tossed a fair coin when you weren’t around.

Let A be the event that she said the outcome is head

B1 = Event she lied and B2 = Event she did not lie

$P(B1) = \frac{1}{3} \\ P(B2) \frac{2}{3}$

P(AB1) = $\frac{1}{2} *\frac{1}{3} =\frac{1}{6}$

P(AB2) = $\frac{2}{3} \frac{1}{2} =\frac{2}{6}$

Required probability = P(B1/A)= $\frac{P(B1A)}{P(B1A)+P(B2A)} \\=\frac{\frac{1}{6} }{\frac{1}{6}+\frac{2}{6}} \\=\frac{1}{3}$
