Agata [3.3K]

Answer:

Solution,

ABCD is a rectangle.

Given,

AC= 64 cm

AB= 50 cm

To find: Value of other side of TV

since, ABCD is a rectangle

<B= 90°

<h3>Using Pythagorean theorem:</h3>

${ac}^{2} = {ab}^{2} + {bc}^{2} \\ {64}^{2} = {50}^{2} + {bc}^{2} \\ {bc}^{2} = {64}^{2} - {50}^{2} \\ {bc}^{2} = 4096 - 2500 \\ {bc}^{2} = 1596 \\ bc = \sqrt{1596} \\ bc = 39.94 \: cm$

Hope this helps...

Good luck on your assignment..

What is the length of a line segment with endpoints (-3, 2) and (5, -1)

TiliK225 [7]

Answer:

The length of the given line segment is $\sqrt{73}$ cm

Step-by-step explanation:

Given end points are (-3,2) and (5,-1)

To find the length of a line segment with these given end points

By using the distance formula we can calculate the length of a line segment

$d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}$

Let $(x_{1},y_{1})$ and $(x_{2},y_{2})$ be the two end points (-3,2) and (5,-1) respectively

$d=\sqrt{(5-(-3))^2+(-1-2)^2}$

$=\sqrt{(5+3)^2+(-3)^2}$

$=\sqrt{(8)^2+(3)^2}$

$=\sqrt{64+9}$

$=\sqrt{73}$

Therefore $d=\sqrt{73}$ units

Therefore the length of a given line segment is $\sqrt{73}$ cm
