Consider a triangle with angles 30o-60o-90o, with hypotenuse of length 2. Calculate the lengths of the other 2 sides and store t

kumpel [21]

Answer:

1.00 and 1.73

Step-by-step explanation:

1) Calculating the 1st and the 2nd leg using trigonometric function sine:

$sin (30^{0})=\frac{c}{2}\Rightarrow \frac{1}{2}=\frac{c}{2}\Rightarrow 2*\frac{1}{2}=2*\frac{c}{2}\Rightarrow c=1\\sin(60^0)=\frac{b}{2}\Rightarrow \frac{\sqrt{3}}{2}=\frac{b}{2}\Rightarrow b=\sqrt{3}\Rightarrow\: b\approx \:1.73$

Once one leg is found there is another way to find the other leg, using Pythagorean Theorem too.

$a^{2}=b^{2}+c^{2}\Rightarrow 2^{2}=b^{2}+1^{2}\Rightarrow 4-1=b^{2}\Rightarrow b=\sqrt{3} b\approx 1.73$

a hypotenuse: 2.00

b leg: 1.73

c leg: 1.00

Sphere B is the image of sphere A after dilation by a scale factor of 44. If the surface area of sphere B is 432 km^2, find the

Sergeeva-Olga [200]

<h2>Answer:</h2>

27 km²

<h2>Step-by-step explanation:</h2>

$SA=4\pi Jr^2$

$4\pi r^2_B=432$

$r^2_B=\frac{108}{\pi}$

$r_B=\frac{6\sqrt3}{\sqrt{50}}$

$r_A=\frac{r_B}{4}=\frac{3\sqrt3}{2\sqrt\pi}$

$S_0SA=4\pi Y\begin{matrix}2\\A\\\end{matrix}$

$=4\pi\bullet\frac{27}{4\pi}$

$=27\ km$

$Y_B:Y_A=4=1$

$SA_B:SA_A=16:1$

$432\div 16=27\ km^2$

$simple\ relation.$

Markup,Discount, Tax find the selling price of each item. Coast of a wagon 229.50 markup 60%

Charra [1.4K]

To find out how much a 60% discount for a wagon that is $229.50, you will have to figure out how to find the discount. First we will find the discount.

229.50 × 0.60 = 137.70

Now, you will subtract that number from the original price

229.50 - 137.70 = 91.80

Now after the discount of 60% the wagon is now $91.80
