Given that the angle is 25 degrees, we shall apply cosine rule to solve this question.
c^2=a^2+b^2-2abcosC
thus plugging the values we get:
15^2=x^2+20x^2-40xcos25
x^2-36.252x+175=0
thus solving the quadratic using quadratic formula we obtain:
x=[36.252+/-√614.208]/2
x=5.7 km or 30.5 km
Answer:

39
hope this will help u
First number:
5+4=9
9-1=8
8 could be a number in the pattern.
You can do 12/12 8/8 10/10 3/3 and 2/2 all equal to 6/6 all in different ways.
Answer:
0.675
Step-by-step explanation:
27/40
- Divide each number by 10
2.7/4
- Multiply each number by 25
67.5/100
Convert that into a decimal. :)
