Answer:
0.40 foot
Step-by-step explanation:
In the first case, a 50 - foot building casts a- foot shadow (1-foot). Let the angle of elevation of the sun from the shadow be represented by θ.
Then:
Tan θ =
Tan θ =
Tan θ = 50
⇒ θ = 50
= 88.8542
=
The angle of elevation is approximately .
For a 20-foot pole,
Tan θ =
Tan =
x =
= 0.4015
= 0.40 foot
The length of the shadow of the pole is 0.40 foot.
Answer:
Step-by-step explanation:
Formula = a^2 + b^2 = c^2
Putting values
= (31)^2 + (48)^2 = (51)^2
= 961 + 2304 = 2601
= 3265 = 2601
Both sides are not equal so it is not a right triangle
Answer
Formula
where r is the radius of a circle.
As shown in the image
Diameter of the circle = 16 .3 cm
= 8.15 cm
Put in the formula
As
= 51.2 cm (approx)
Therefore the circumference of a circle is 51.2cm (approx) .
Option (D) is correct .
The answer to this question is: 15
