Rotate RST 90° counterclockwise around the origin.<br>

Nostrana [21]

The image of the triangle RST when rotated 90° counterclockwise around the origin is (-15,5), (-15,15) and (-5,10)

<h3>
How to rotate the triangle?</h3>

The coordinates of RST are given as:

R = (5,15)

S = (15,15)

T = (10,5)

The rule of 90° counterclockwise around the origin is:

(x,y) -> (-y,x)

So, we have:

R' = (-15,5)

S' = (-15,15)

T' = (-5,10)

Hence, the image of the triangle when rotated 90° counterclockwise around the origin is (-15,5), (-15,15) and (-5,10)

Find the missing part. L=8, w=4, h=2. Find the diagonal of (d) of the retangular solid

marusya05 [52]

The diagonal of the rectangular solid is $d=2 \sqrt{21}$

Explanation:

The length of the rectangular solid is $l=8$

The width of the rectangular solid is $w=4$

The height of the rectangular solid is $h=2$

We need to determine the diagonal of the rectangular solid.

The diagonal of the rectangular solid can be determined using the formula,

$d=\sqrt{l^{2}+w^{2}+h^{2}}$

Substituting the values $l=8$ , $w=4$ and $h=2$ , we get,

$d=\sqrt{8^{2}+4^{2}+2^{2}}$

Squaring the terms, we get,

$d=\sqrt{64+16+4}$

Adding the terms, we have,

$d=\sqrt{84}$

Simplifying, we have,

$d=2 \sqrt{21}$

Thus, the diagonal of the rectangular solid is $d=2 \sqrt{21}$
