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,

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

⇒ $tan x =\frac{AB+BC}{DC}$

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

⇒ $tan x =\frac{27.4866988101}{19.6}$

⇒ $tan x =1.40238259235$

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

Which equation correctly uses point (–2, –6) to write the equation of this line in point-slope form? Y – 6 = y minus 6 equals St

GenaCL600 [577]

Answer:

Part 1) $y+6=\frac{2}{5}(x+2)$

Part 2) $y+6=\frac{5}{2}(x+2)$

Step-by-step explanation:

The equation of the line in point slope form is

$y-y1=m(x-x1)$

we're going to analyze two cases

<em>First case</em>

$Point\ (-2,-6)$

$slope\ m=\frac{2}{5}$

substitute

$y+6=\frac{2}{5}(x+2)$

therefore

y plus 6 equals StartFraction 2 Over 5 EndFraction left-parenthesis x plus 2 right parenthesis

<em>Second case</em>

$Point\ (-2,-6)$

$slope\ m=\frac{5}{2}$

substitute

$y+6=\frac{5}{2}(x+2)$

therefore

y plus 6 equals StartFraction 5 Over 2 EndFraction left-parenthesis x plus 2 right parenthesis
