Answer:
I just learned this about a few weeks ago I hope this helps.
Step-by-step explanation:
Since it's cosine you're only looking at Adjacent and the hypotenuse which the adj is 20 and the hyp is 25 so since cosine is adj/hyp you do 20/25 then simplify it to 20/25 divide both by 5 so it's simplified to 4/5.
Then you do Cos-1(4/5)=36.869 which is rounded to the tenth 36.9 but rounded to the hundredth 36.87.
Hope this helps
I think that x may equal to -3. Because the sum of a triangle is always 180. 55+54=109 and 180-109=71 and -3+74=71
Correct answer is B
10/15=.666
This is RW divided by RT
Now you have to use the scale factor. Multiply by 18 to get WV
18 x 0.666 = 12
Good Luck Thnks for brainiest :)
Answer:
10+6+9+5= 40
So there are
are yellow cards
are green cards
are orange cards
red cards
now we have to get the percentages
=
=
=
=
so the probability of getting...
<u>yellow is 25%</u>
<u>green is 15%</u>
<u>orange is 22.5%</u>
<u>red is 12.5%</u>
