In the given figure, O is centre of the circle. Find the value of x and y? ​
Effectus [21]

Answer:

The value of x = 13cm and y = 12cm.

Step-by-step explanation:

P is the exterior point to the circle with centre O

Radius = 5cm

Length of the tangent = 12 cm

Distance between the point and centre of the circle = x cm

We know that

The angle between the radius of the circle and the tangent at the point of contact is 90°

By Pythagoras Theorem

Hypotenuse² = Side²+Side²

⇛x² = 12²+5²

⇛x² = 144+25

⇛x² = 169

⇛x² = 13²

<h3>⇛x = 13 cm</h3>

We know that

The lengths of tangents drawn from the exterior point to the circle are equal.

<h3>y = 12 cm</h3>

<u>Answer</u><u>:</u> The value of x=13cm and y = 12cm.

Is the set of numbers one 1,5,25 and 125 a geometric sequence
Strike441 [17]
Short answer: Yes.
Each member of the sequence is multiplied by 5 to get to the next member of the sequence.

Find the general equation.
tn = a*5^(n - 1)

Example
t4 = 1*5^(4 - 1)
t4 = 1*5^3
t4 = 125 just as the sequence shows.

t5 = 1^5^4
t5 = 625     Any member of the sequence can be found this way.

Find the distance x rounded to<br> the nearest tenth.
anyanavicka [17]

Answer:

x=0.1 ~ft

Step-by-step explanation:

cot30=\frac{B}{H} =\frac{B}{H}

\frac{\sqrt{3} }{2} =\frac{B}{H}=H=\frac{16}{\sqrt{3} }

sin70=\frac{X}{H} =\frac{P}{H}

sin70=\frac{x}{\frac{16}{\sqrt{3} } }

x=\frac{\sqrt{3} }{16 ~sin70}

=0.1152

x=0.1

hope it helps

have a great day!!
