31.4 cm
Step-by-step explanation:
the radius is 5 so the diameter is 10 so you'll have to multiply 3.14 by 10 not 5
Answer:
12a+60 i think lol
Step-by-step explanation:
this is how i did it though:
12(a+b)
12a+60
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°
