Quadrilateral ABCD is inscribed in this circle.

Svetllana [295]

Answer:

132°

Step-by-step explanation:

Quadrilateral ABCD is inscribed in a circle,

So, it is a cyclic quadrilateral.

Opposite angles of a cyclic quadrilateral are supplementary.

$\implies \: x \degree + (3x - 12) \degree = 180 \degree \\ \\ \implies \: (4x - 12) \degree = 180 \degree \\ \\ \implies \: 4x - 12 = 180 \\ \\ \implies \: 4x = 180 + 12 \\ \\ \implies \: 4x = 192 \\ \\ \implies \: x = \frac{192}{4} \\ \\ \implies \: x = 48\\\\$

(3x-12)° = (3*48 - 12)° = (144 - 12)° = 132°

$\implies \: m\angle B = 132\degree\\\\$

oee [108]

Let
x-----------> the first number
y-----------> the second number

we know that
x*y=x-----------> y=x/x----------> y=1
and x+y=y------> x=y-y---------> x=0

the answer is
 the first number is 0
the second number is 1

[[Please Explain]] The equation y - 2/3 = -2 (x - 1/4) is written in point-slope form. What is the equation in slope-intercept f

alexira [117]

Slope-intercept form is just solving for y in point-slope form

y - 2/3 = -2 (x - 1/4)

First you distribute the -2 because it is the first order of operation

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

Then you add 2/3 on both sides because we want to isolate y

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

Then we combine like terms

y = -2x + 7/6
