Answer:

Option 4: <u>(2x + 16)° + (x)° = 180°</u>

Step-by-step explanation:

See the attached figure.

For a quadrilateral inscribed in a circle

The opposite angles are supplementary.

So, ∠D + ∠B = 180°

From the figure:

∠B = x° and ∠D = (2x+16)°

∴ <u>(2x + 16)° + (x)° = 180°</u>

What’s the answer to 14

mars1129 [50]

Step-by-step explanation:

EF = 6x - 4

and it is also the combination of EG and GF.

so,

6x - 4 = EG + GF = EG + 13

6x = EG + 17

now, we have additional information. EF bisects CD. that means it cuts CD in half.

and that means both banks must be off equal size.

5x - 1 = 7x -13

12 = 2x

x = 6

so, back to the first problem

6×6 = EG + 17

36 = EG + 17

19 = EG

Answer: $5x-3y=44$

Step-by-step explanation:

We know that , the equation of a line that passes through (a,b) and (c,d) is given by :_

$(y-b)=\dfrac{d-b}{c-a}(x-a)$

Standard form of equation of line = $Ax+By=C$

Given points = (7, -3) and (4, -8)

Then, the equation of a line that passes through the points . (7, -3) and (4, -8) is given by -

$(y-(-3))=\dfrac{-8-(-3)}{4-7}(x-7)$

$(y+3)=\dfrac{-8+3}{-3}(x-7)$ [∵ (-)(-)=(+)]

$(y+3)=\dfrac{-5}{-3}(x-7)$

$(y+3)=\dfrac{5}{3}(x-7)$

$3(y+3)=5(x-7)$

$3y+9=5x-35$

$9+35=5x-3y$

$44=5x-3y$

Or $5x-3y=44$

Hence, the required equation :- $5x-3y=44$
