5. Lila flies a drone in the direction of 90 degrees towards Avery. Once she gets to Avery she changes course and flies in the d
disa [49]

Answer:

Mark and Lila are 29.83 meters apart.

Step-by-step explanation:

If we draw a triangle with the information given (see image attached), we have that the angle Lila-Avery-Mark is equal to 70°. Then, to find the distance between Mark and Lila, we just need to use the law of cosines, using the two sides given and the angle between them:

c^2 = a^2 + b^2 - 2*a*b*cos(C)

c^2 = 30^2 + 20^2 - 2*30*20*cos(70)

c^2 = 900 + 400 - 1200*0.342

c^2 = 889.6

c = 29.83 m

Mark and Lila are 29.83 meters apart.

Two equations are given below:
Vadim26 [7]
For this equation, we can just plug in the equation of m in for m. This makes the equation: n - 2 + 3n = 10. We then only have to solve for n. We add 2 to both sides, making it n + 3n = 12, is which is also 4n = 12. We then divide both sides by 4, getting n = 3. The only answer saying n = 3 is the first.
