Answer:

$52.53\ \text{meters}$

Step-by-step explanation:

$1\ \text{meter}=100\ \text{centimeter}$

$1\ \text{centimeter}=\dfrac{1}{100}\ \text{meter}$

In the question the quantity that is required to be converted to meters is 5253 centimeters.

$5253\ \text{cm}=5253\times \dfrac{1}{100}\\ =52.53\ \text{meters}$

So, the required measurement in meters is $52.53\ \text{meters}$ .

The longer leg of a 30,-60,-90 degree triangle is 18: what is the length of the other leg

taurus [48]

Answer:

The other legs are 9 and 9√3

Step-by-step explanation:

The longer side of a 30-60-90 degree rectangle is 18.

The other legs will be

$\frac{x}{2}$

and

$\frac{x}{2} \sqrt{3}$

Where x is the longest side, which is given as 18.

Therefore one leg will be:

$\frac{18}{2} = 9$

and the other leg will be:

$\frac{18}{2} \sqrt{3} = 9 \sqrt{3}$
