The sine of any angle is equal to the cosine of the complementary angle.

Complementary angle means two angles whose total equal to 90 degrees.

The complementary angle for 30 degrees is 90 degrees - 30 degrees or 60 degrees.

So, sin(30) = cos(60).

12) A radio transmission tower is 170 feet tall. How long should a guy wire be if it is to be attached 15 feet from the top and
ser-zykov [4K]

The length of guy wire needed to make an angle of 30° with the ground is 310 feet. The angle between the end of the shadow and the vertical side of the building is 23°

<h3>What is trigonometric ratio?</h3>

Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.

a) Let l represent the length of the guy wire.

sin(30) = (170 - 15) / l

l = 310 feet

b) Let Ф represent the angle, hence:

tanФ = 100/230

Ф = 23°

The length of guy wire needed to make an angle of 30° with the ground is 310 feet. The angle between the end of the shadow and the vertical side of the building is 23°
