Long Piece: 5x
Short Piece: x
(x) + (5x) = 72
6x = 72
x = 12
Long Piece: 5x = 5(12) = 60
Answer: 12 cm and 60 cm
Answer:
m=21
Step-by-step explanation:
Let the angle of elevation is x and the height of the rocket from the ground is y
tanx = y/15
by differentiating both sides with respect to T
sec²x·dx/dt = (dy/dt)/15
at y = 30 , the hypotenuse of the triangle = 15√5
sec²x=(15√5/15)²=5
5 dx/dt = 11/15
dx/dt = 11/75 rad/sec
