Answer:
yuh
Step-by-step explanation:
Decompose each velocity in its i and j - coordinates.
1) River's velocity
3.5 m/s, west fo east = 3.5i + 0j
2) Luke's velocity
5m/s, 60° east of north
5* sin(60°) i + 5*cos(60°) j = 4.33 i + 2.5 j
3) Resultant velocity
[3.5i + 0j] + [4.33i + 2.5j] = 7.83i + 2.5j
resultant speed = √[ (7.83)^2 + (2.5)^2 ] = 8.22 m/s
angle = arctan(2.5 / 7.83) = 17.7° north of east (equal to 72.3° east of north).
Answer:
C=G=80°
Step-by-step explanation:
C=180°-(A+B)
G=180°-(E+F)
Because the sum of three angles of any triangle adds up to 180°
Answer:
3 courts
Step-by-step explanation:
8,000 = 1 court
24,000 = x courts
8,000 x ? = 24,000
8,000 x <u>3</u> = 24,000
1 x 3 = 3 courts
