Answer:
The height of the building that casts a shadow of 78m meters is 39m
Step-by-step explanation:
Let height be represented by H and the shadow is S
as they are directly proportional
H s
H=KS ( where K is a proportionality constant)
H=2.5m , S= 5m
On substituting in the equation
2.5 = K*5
K= 0.5
Now the equation becomes
H = 0.5*S
Height when shadow is 78m
H= 0.5*78
H= 39m
Answer:
The length of HF is 73.9 feet.
Step-by-step explanation:
Let the length of HF be represented by x. So that applying the appropriate trigonometric function to the triangle FGH, we have;
Sin θ =
Where θ is the angle given in the triangle = .
Then,
Sin 80 =
⇒ x = Sin 80 x 75
= 0.9848 x 75
= 73.86
x = 73.9
Thus, the length of HF is 73.9 feet.
