This is the answer: X= 118
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 :)

Answer: 1
Step-by-step explanation:
Find (d + c)(3) The x value is 3 so you plug in 3 for the x's in the equation
d(x) = 2x − 4
d(3) = 2(3) - 4
d(3) = 2
c(x) = 2x − 7
c(3) = 2(3) - 7
c(3) = -1
Now you plug in the value of d and c into your original equation which is (d+c)(3)
(2 + (-1)) = 1
This means (d+c)(3) = 1
