Phantasy [73]

Answer:

$14 units$

Step-by-step explanation:

$Solution:-$

$A(5,1)B(7,1)$

$\sqrt{(x_{1}-x_{2} ) ^{2}(y_{2} -y_{1}x^{2} }$

$AB=\sqrt{(7-5)^{2} +(1-1)^{2} }$

$= \sqrt{2^{2} } =2$

$BC=\sqrt{7-7^{2}+(6-1)^{2} }$

$=\sqrt{5^{2} } =5$

$perimeter=2(AB)+2(BC)$

$= 2(2)+2(5)\\$

$= 4+10= 14$

$-----------$

hope it helps...

have a great day!!

your drawer contains 6 black socks and 8 white socks. what is the probability that both socks are black

Nimfa-mama [501]

$\displaystyle |\Omega|=\binom{14}{2}=\dfrac{14!}{2!12!}=\dfrac{13\cdot14}{2}=91\\ |A|=\binom{6}{2}=\dfrac{6!}{2!4!}=\dfrac{5\cdot6}{2}=15\\\\ P(A)=\dfrac{15}{91}\approx16\%$

The string of a kite is 120 metres long and it makes an angle of 60 degree

Afina-wow [57]

Answer:

103.92 m

Step-by-step explanation:

The kite is making right angle with the ground and its string is acting as hypotenuse of right triangle.

Let the height of the kite from the ground be h meters.

Therefore, by trigonometrical ratio:

$\sin \theta \: = \frac{height \: of \: the \: kite}{length \: of \: the \: string} \\ \\ \sin 60 \degree \: = \frac{h}{120} \\ \\ \frac{ \sqrt{3} }{2} = \frac{h}{120} \\ \\ h = \frac{ \sqrt{3} }{2} \times 120 \\ \\ h = \sqrt{3} \times 60 \\ \\ h = 1.732 \times 60 \\ \\ h = 103.92 \: m \\$

Thus, the height of the kite from the ground is 103.92 meters.
