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.
Answer:
Distance between NY and Boston on map(in cm) is, 25.5 cm
Step-by-step explanation:
Given:
1 cm = 1200000 cm
Using conversion : 1 km = 100000 cm
1 cm = 12 km
or we can write it as:
12 km = 1cm
306 km = cm (∴by unitary method)
Therefore, the distance between NY and Boston on map(in cm) is, 25.5 cm
