Answer:

x = 4 $\sqrt{3}$ in

Step-by-step explanation:

Given a tangent and a secant to the circle from an external point, then

The square of the tangent is equal to the product of the secant's external part and the entire secant, that is

x² = 4(4 + 8) = 4 × 12 = 48 ( take the square root of both sides )

x = $\sqrt{48}$ = $\sqrt{16(3)}$ = $\sqrt{16}$ × $\sqrt{3}$ = 4 $\sqrt{3}$ ← exact value

Write the equation of the line that passes through the point (3,5) and is perpendicular to the line y=3.

3241004551 [841]

Answer:

x = 3

Step-by-step explanation:

y = 3 is the equation of a horizontal line parallel to the x- axis.

A line perpendicular to it must therefore be a vertical line parallel to the y- axis with equation

x = c

where c is the value of the x- coordinates the line passes through.

The line passes through (3, 5) with x- coordinate 3 , thus

x = 3 ← equation of perpendicular line

Given:

A quadrilateral inscribed in a circle.

To find:

The value of x and y.

Solution:

If a quadrilateral inscribed in a circle, then it is known as cyclic quadrilateral and the opposite angles of a cyclic quadrilateral are supplementary angles, it means their sum is 180 degrees.

$5x^\circ+110^\circ=180^\circ$ [Supplementary angles]

$5x^\circ=180^\circ -110^\circ$

$x^\circ=\dfrac{70^\circ}{5}$

$x^\circ=14^\circ$

The value of x is 14 degrees.

$2y^\circ+104^\circ=180^\circ$ [Supplementary angles]

$2y^\circ=180^\circ -104^\circ$

$y^\circ=\dfrac{76^\circ}{2}$

$y^\circ=38^\circ$

Therefore, the value of x is 14 degrees and the value of y is 38 degrees.

Solve the following equation for the unknown quantity: 12x-8=3x+10. a. x=4 b. =2 c =12 d. x=1/2

dezoksy [38]

Answer:

b. x=2

Step-by-step explanation:

Step 1- Move the variable to one side.

12x-8= 3x+10

-3x -3x

9x-8= 10

Step 2- Add 8 to both sides.

9x-8= 10

+8 +8

9x= 18

Step 3- Divide to both sides.

9x= 18

9 9

x= 2
