Answer:

Step-by-step explanation:

finding PR ( public relations :D , not that PR , the PR on this triangle thingy )

use law of cosines, again

c=sq rt [ a^2+b^2﹣2*a*b*cos(C) ]

where

c=PR

a= 9

b = 22

C = the angle of Q or 180 = 97+24+Q so Q = 180-97-24 = 59°

they tried to trick us.. by not giving us the angle C for the above cosine formula , but we figured out their diabolical plan :D yay super hero math

then

PR = sq rt [ 9^2 + 22^2 - 2*9*22*cos(59) ]

PR = sq rt [ 81 + 484 -203.9550777 ]

( notice that now it is a subtraction sign instead of a plus sign, this time? )

PR = sq rt [361.0449 ]

PR = 19.0011

to the nearest 10th

19.0 :)

RUDIKE [14]

Answer:

3/5

Step-by-step explanation:

Using SOHCAHTOA, we know that cos Ф = $\frac{adjacent-side}{hypotenuse}$

So, we know that cos Ф = $\frac{3}{5}$ or, using the hint, 3/5

Answer:

21.8 m/s

Step-by-step explanation:

Given that Tom drops a object from a height of h meters and it hits the ground with a veloc8of v m/s and it is given by function ;

$\longrightarrow v =\sqrt{19.6h}$

We need to find out the velocity upon reaching the ground when it is dropped from a height of 24.3 m . On plugging in 24.3 in place of h we have ,

$\longrightarrow v =\sqrt{19.6\times 24.3 }\ m/s\\\\\longrightarrow v =\sqrt{ 476.28} m/s \\\\\longrightarrow v = 21.823 \ m/s \\\\\longrightarrow \underline{\underline{ v = 21.8 \ m/s }}$

And we are done !

Answer:

B. 0

Step-by-step explanation:

2-2/5-2= 0/3= 0

Another way to look at this is that because they have the same y coordinate, it must simply be a horizontal line, which has a slope of 0
