Answer:

We know that tan A = opposite side / adjacent side

Using 30 , 60 , 90 theorem

side opposite to 60 is root 3x and adjacent side is x

Tan 60 = root 3x / x

= root 3

so root 3 is your required answer

distance = 500 feet

Since Δ VWX and Δ YZX are similar then the ratios of corresponding sides are equal, that is

$\frac{VW}{YZ}$ = $\frac{VX}{YX}$ = $\frac{WX}{ZX}$

completing the required values gives

$\frac{100}{l}$ = $\frac{60}{30}$ ( cross- multiply )

60l = 30 × 100 = 3000 ( divide both sides by 60 )

l = 500

Answer:

π = S/2πrh
v = √2E/m
b = (-7a+c)/2
x =3y-1

Step-by-step explanation:

$S = 2\pi rh\\Divide\:both\sides\:of\:the\:equation\:by\:2rh\\\\\frac{S}{2rh} = \frac{2 \pi rh}{2 rh} \\\\\pi = \frac{S}{2rh}$

$E = \frac{1}{2} mv^2\\\\E = \frac{mv^2}{2} \\\\Cross\:multiply\\\\2E =mv^2\\Divide\:both\:sides\:of\:the\:equation\:by\:m\\\frac{2E}{m} = \frac{mv^2}{m} \\\\\frac{2E}{m} =v^2\\Square\:root\:both\:sides\:of\:the\:equation\\\sqrt{\frac{2E}{m} } = \sqrt{v^2} \\\\\sqrt{\frac{2E}{m} } =v\\\\v =\sqrt{\frac{2E}{m} }$
