Use trig to find the legs of ABC if the base is AC and the height is BC (round to nearest tenth)

umka2103 [35]

Answer:

<u>GIVEN :-</u>

∠A = 15°
Length of AB (hypotenuse) = 60 ft

<u>TO FIND :-</u>

Length of BC
Length of AC
Area of ΔABC

<u>FACTS TO KNOW BEFORE SOLVING :-</u>

$\sin \theta = \frac{Side \: opposite \: to \: \theta}{Hypotenuse}$
$\cos \theta = \frac{Side \: adjacent \: to \: \theta}{Hypotenuse}$

<u>SOLUTION :-</u>

In ΔABC ,

$\sin 15 = \frac{BC}{60}$

$=> 0.2588... = \frac{BC}{60}$

$=> BC = (0.2588....) \times 60 = 15.5291.....$ ≈ 15.5 ft

$\cos 15 = \frac{AC}{60}$

$=> 0.9659..... = \frac{AC}{60}$

$=> AC = (0.9659.....) \times 60 = 57.9555.....$ ≈ 58 ft

Area of ΔABC = $\frac{1}{2} \times 58 \times 15.5 = 449.5 \:ft^2$

2. Find the values of x and y.

AlexFokin [52]

Answer:

x = √2, y = 2

Step-by-step explanation:

You know that the sides of an isosceles right triangle are equal in length, so ...

x = √2 . . . . same as the given side

You also know that the hypotenuse is √2 times as long as one side, so ...

y = √2·√2

y = 2

3. Red candy costs $2.50 per pound. Green candy costs $4.75 per pound. You bought ten pounds of candy for $38.50. How many pound

Aloiza [94]

Answer:

6 pounds of green candy

Step-by-step explanation:

Let r be the weight of red candy

Let g be the weight of green candy

Total weight = 10 pounds

r + g = 10 -------------------------(I)

Total cost = $ 38.50

2.50r + 4.75g = 38.50 --------------(II)

Multiply equation (I) by -2.50

(I)* (-2.50) -2.50r - 2.50g = -25.0

(II) <u>2.50r + 4.75g = 38.50 </u> {Now add and r will be eliminated}

2.25g = 13.50

g =13.50/2.25

g = 6

Plug in the value of g in equation (I)

r + 6 = 10

r = 10 - 6

r = 4
