It is LCM=180 I'm pretty sure
Answer:
DA = 285.7 m
Step-by-step explanation:
First we need to find the side AB in the triangle ABC, and we can do this using Pythagoras' theorem:
AB^2 = BC^2 + AC^2
AB^2 = 300^2 + 400^2
AB^2 = 25000
AB = 500 m
We can find the angle ABC with the tangent relation:
tangent(ABC) = 400/300 = 4/3
ABC = 53.13°
From triangle ABC, we have:
ABC + BCA + CAB = 180°
53.13 + 90 + CAB = 180
CAB = 36.87°
From triangle DAC, we have:
DAC + ACD + CDA = 180
36.87 + 45 + CDA = 180
CDA = 98.13°
Now to find the side of DA, we can use law of sines in triangle DAC:
DA/sin(DCA) = AC/sin(CDA)
DA/sin(45) = 400/sin(98.13)
DA = 400 * 0.7071 / 0.9899 = 285.7258 m
Rounding to nearest tenth, we have DA = 285.7 m
Answer:
n=16
Step-by-step explanation:
Hello ,
v is greater than or equal to 5
v ≥ 5 .
Answer:
10*7+ 18x *7 =2590
or 70 + 18x*7 =2590
Step-by-step explanation:
10*7 to find out how much the shipping costs for the 7 teams altogether
18*x because you need to find how much the jerseys cost for all the soccer teams
then multiply it by 7 to find how many players on each team
when you solve for x you get 20
there are 20 players on each on team.
