Answer:

52 km.

Step-by-step explanation:

$a^{2} + b^{2} = c^{2}$

$165^{2} + x^{2} = 173^{2}$

$27225 + x^{2} = 29929$

$x^{2} = 2704$

$x = \sqrt{2704}$

$x = 52$

Given the endpoint (-9,3) and (1,8) partition the segment into the ratio 2:3<br>

Sindrei [870]

Answer:

$P = (-5,5)$

Step-by-step explanation:

Let the segments be A and B

$A = (-9,3)$

$B = (1,8)$

$m:n = 2:3$

Required

Determine the endpoints after it is divided into ratios.

<em>Let the point be represented with P</em>

The formula to use is:

$P = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})$

Where

$A = (-9,3)$ ----- $(x_1,y_1)$

$B = (1,8)$ ------ $(x_2,y_2)$

So:

$P = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})$

$P = (\frac{2 * 1 + 3 * -9}{2 + 3},\frac{2 * 8 + 3 * 3}{2 + 3})$

$P = (\frac{-25}{5},\frac{25}{5})$

$P = (-5,5)$

Answer:

14)

21√2

15)

Leg: 7√3

Hypotenuse: 14

Step-by-step explanation:

The hypotenuse is √2 as long as each leg. That means the leg is 42/√2. Simplified to make 21√2.

The hypotenuse is always twice as long as the shortest leg on a 30-60-90 triangle. The longer leg is √3 as long as the shortest side.
