the answer is 7
Step-by-step explanation:
angle 30°
x=14/2
x=7
Answer:
27 I think just divide 81 by 3
Answer:
-18
Step-by-step explanation:
You can basically just drop the plus sign and remove the parenthesis because the plus sign doesn't alter negatives.
-6+(-12)
-6-12= -18
Answer:
Step-by-step explanation:
In parallelogram, opposite sides are parallel and equal
3x + 7 = 5x -17
3x - 5x = -17 - 7
-2x = - 24
x = -24 /-2
x = 12
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 :)
