SOH - CAH - TOA
We need to know the shadow length, which is adjacent to the angle we are given. We are also given the height of the building, which is opposite of the angle. Using both of these, we can find the shadow length:
tan 25 = 100/A
A = 100/ tan 25
A = 214.5 ft
Answer:
Option 3.
Step-by-step explanation:
It is given that a triangle sits on a line and forms 2 exterior angles on the left and right of the triangle of (2h) degrees.
The top interior angle of the triangle is 40 degrees.
From the given figure it is clear that
(Supplementary angle)
(Supplementary angle)
According to the angle sum property of triangle, the sum of all interior angles of a triangle is 180 degree.
Combine like terms.
Divide both sides by -4.
The value of h is 55.
Therefore, the correct option is 3.
