Answer:
x = 26
Step-by-step explanation:
Since the triangle is right, use Pythagoras' identity to find x
x² = 24² + 10² = 576 + 100 = 676
take the square root of both sides
= 
, hence
x = 26
You might want to look up some webstite that explains how to do it. thats how i learned area. I know the answer but i like to draw it out
Each packet will equal to weigh a total of
1/16 of a pound.
This is because 1/2 a pound divided by 8 packets equals to 1/16 of a pound.
Answer:
Step-by-step explanation:
The questions asks for how far down the wall does the ladder move, so to say that in another way, what is the difference between when the ladder is taller up the wall and when it is shorter up the wall.
so figure out what the height of the ladder is up the wall for each of the situations.
1) Taller
we are told the Hyp and the Adj sides of the triangle
so use SOH CAH TOA to remind how trig functions fit on the triangle sin = Opp / Hyp , Cos=Adj / Hyp , Tan = Opp / Adj so
Cos(Ф) = 7 / 25
Ф = arcCos( 7/25)
Ф = 73.739795 °
then use
Sin( 73.739795 ) = Opp / 25
25* Sin( 73.739795 ) = Opp
24 = Opp
2) Shorter
Cos(Ф) = 15 / 25
Ф = arcCos( 15 / 25 )
Ф = 53.13010 °
sin( 53.13010 ) = Opp / 25
25 * sin( 53.13010 ) = Opp
20 = Opp
now you know the two heights up the wall. so subtract the shorter from the taller
24 - 20 = 4
the ladder moves 4 feel down the wall :)
Answer:
the probability is 
Step-by-step explanation:
there are 4 numbers on a 12 sided die that can be divided by 3: 3, 6, 9, and 12.
so the probability would be
