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 :)
There are 4 choose 3 ways to hold 3 kings and 4 possible queens to make up the fourth card of the hand out of a total of 54 choose 4 possible four-card hands, which gives us the following expression for the probability of being dealt 3 kings and a queen out of 4 cards: Or roughly 1 in every 16920 four card hands.
Answer:
Step-by-step explanation:
step 1
Find the length side c
Applying the law of sines
substitute he given values
solve for c
step 2
Find the measure of angle B
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
so
substitute the given values
step 3
Find the area of the triangle
we know that
The area of the triangle applying the law of sines is equal to
substitute the given vales
