Answer:

Step-by-step explanation:

If a quadrilateral is inscribed in a circle with all four edges touching the circumference of the circle, then the opposite angles are supplementary. This means that the sum of the opposite angles is 180 degrees. Therefore,

Angle B + angle D = 180

Angle A + angle C = 180

3x + x + 20 = 180

4x = 180 - 20 = 160

x = 160/4

x = 40

Angle A = 2 × 40 + 78 = 158 degrees

Angle B = 3 × 40 = 120 degrees

Angle C = 180 - 158 = 22 degrees

Angle D = 40 + 20 = 60 degrees

What is the logarithmic form of the solution to 102t = 9?

Harman [31]

Equivalent equations are equations that have the same value

The equation in logarithmic form is $t = \frac{\log(9)}{2}$

<h3>How to rewrite the equation</h3>

The expression is given as:

$10^{2t} = 9$

Take the logarithm of both sides

$\log(10^{2t}) = \log(9)$

Apply the power rule of logarithm

$2t\log(10) = \log(9)$

Divide both sides by log(10)

$2t = \frac{\log(9)}{\log(10)}$

Apply change of base rule

$2t = \log_{10}(9)$

Divide both sides by 2

$t = \frac{\log_{10}(9)}{2}$

Rewrite as:

$t = \frac{\log(9)}{2}$

Hence, the equation in logarithmic form is $t = \frac{\log(9)}{2}$

Find the value of AB.<br> 13<br> 12<br> A<br> В<br> AB = [?

Sedaia [141]

Answer:

$AB=24$

Step-by-step explanation:

CD is perpendicular to AB

If any radius or diameter is perpendicular to any chord of a circle, then it bisects that chord.

Mean, AB= BE = 12

So, AB = 2(BE)

2(12)= 24

so your answer will be 24

Plsss help me graph this!!! Attached is the question

e-lub [12.9K]

The graph is a straight line graph with a slope of -1/2

Equation of a line in point-slope form

The equation of a line in point slope form is expressed as:

y - y₁ = m(x - x₁)

Given the following parameters

Point = (-2, 3)

Slope = -1/2

Substitute the given parameters into the formula

y-3 = -1/2(x-(-2))

y-3 = -1/2(x+2)

Write in slope-intercept form

2(y-3) = -(x+2)

2y-2(3) = -x -2

2y - 6 = -x -2

2y = -x + 4

y = -1/2x + 2

The graph of the equation is as shown below
