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,

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

⇒ $tan x =\frac{AB+BC}{DC}$

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

⇒ $tan x =\frac{27.4866988101}{19.6}$

⇒ $tan x =1.40238259235$

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

FIXED! HELP!Maria bought 1 2/5 pounds of lunch meat for $3.36. How much would 2 3/4 pounds of lunch meat cost? Enter your answer

Vsevolod [243]

We are going to want to change any mixed number into an improper fraction. 2 3/4 is 11/4 and 1 2/5 is 7/5.
We are going to set up a proportion where the lbs are on the top and the money is on the bottom. x is going to be how much it costs for 2 3/4 lbs of lunch meat.

(7/5)/3.36 = (11/4)/x
Cross multiplication \/
7/5x = 9.24
x = 6.60

As a final answer, the 2 3/4 lbs of lunch meat cost $6.60
