9. A person stands at the window of a building so that his eyes are 12.6 m above the level ground. An
object is on the ground 58.5 m away from the building on a line directly beneath the person. Compute
the angle of depression of the person's line of sight to the object on the ground.

25.3

step-by-step explanation:

1st step

add 3+6

=9

multipy 9*3

=37

hint: which coefficient is a multiple of 360°?

step-by-step explanation:

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
