<h2>The sine function won't be affected, but the consine function will.</h2>Step-by-step explanation:
First of all, remember that and
. As you can see, the sine function won't be affect by
, because its value is null.
However, the x-intercept of the cosine function depends on the value, because the function is equal to the unit.
On the other hand, the variable won't affect any function, because it would be always zero.
Therefore, the sine function won't be affected, but the consine function will.
Answer:
30.51 meters
Step-by-step explanation:
Given that:
The distance from the point to the base of the tower = 42 m, the angle of elevation = 36°.
According to sine rule if a,b,c are the sides of a triangle and its respective opposite angles are A, B, C. Therefore:
Let the height of the tower be a and the angle opposite the height be A = angle of elevation = 36°
Also let the distance from the point to the base of the tower be b = 42 m, and the angle opposite the base of the tower be B
To find B, since the angle between the height of the tower and the base is 90°, we use:
B + 36° + 90° = 180° (sum of angles in a triangle)
B + 126 = 180
B = 180 - 126
B = 54°
Therefore using sine rule:
The height of the tower is 30.51 meters
