Calculate m∠ADC. Round to the nearest thousandth.

stira [4]

Answer: $54.508^{\circ}$

Step-by-step explanation:

Let the angle ADC = x degree

Since, By the given diagram, In triangle BDC,

$\frac{BC}{DC} = tan27^{\circ}$

⇒ $\frac{BC}{19.6} = tan27^{\circ}$

⇒ $BC = 19.6\times tan 27^{\circ}$

⇒ $BC = 9.98669881009$

Now, In triangle ADC,

$tan x =\frac{AC}{DC}$

⇒ $tan x =\frac{AB+BC}{DC}$

⇒ $tan x =\frac{17.5+9.98669881009}{19.6}$

⇒ $tan x =\frac{27.4866988101}{19.6}$

⇒ $tan x =1.40238259235$

⇒ $x = 54.508389368\text{ degree} \approx 54.508^{\circ}$

A pair of jeans cost 89. A jean jacket costs twice as much. What is the total cost of a jean jacket and 4 pairs of jeans?

iVinArrow [24]

Jeans=$89 jean jacket=$(89x2)
$178
$(89x4+178)
89
  x4
$ (276 + 178)= $454

total cost = $454

Find and interpret the slope of the line containing the given points. (12,4) and (10,10)

MAVERICK [17]

Answer:

3/-1

Step-by-step explanation:

The slope is 3/-1 (Rise 3 on the y axis, run to the negatives by 1 on the x axis)

To find the slope of two points, use the formula of y2-y1/x2-x1 (For example, with this equation it would be 10-4/10-12)

I'm not sure what it means to interpret the slope, but hopefully this helped you!

Write the equation of the line that contains the given point and has the given slope. (–1, 4), slope is –3

charle [14.2K]

$\bf (\stackrel{x_1}{-1}~,~\stackrel{y_1}{4})~\hspace{10em}slope = m\implies -3\\\\\\ \begin{array}{|c|ll}\cline{1-1}\textit{point-slope form}\\\cline{1-1}\\y-y_1=m(x-x_1)\\\\\cline{1-1}\end{array}\implies y-4=-3[x-(-1)]\\\\\\y-4=-3(x+1)\implies y-4=-3x-3\implies y=-3x+1$
