Answer:
x=28
Step-by-step explanation:
This will involve finding an arctangent.
We'll consider the woman's height as the "opposite" side of a triangle and the shadow as the "adjacent" side. The angle that the Sun makes equals the arc tangent of that angle.
tan (Sun's angle) = 71" / 36"
tan (Sun's angle) =

when we determine the arc tangent of 1.9722222222, it will equal the Sun's angle.
arc tangent of 1.9722222222 = 63.113 degrees

Answer:
x = 5
Step-by-step explanation:
3x = 15 (divide both sides by 3)
x = 15/3
x = 5
Answer:
Assuming the triangle is an equilateral triangle (all sides and angles are equal), <u>the equation 3x = 20</u> would be used to find the length of each side.
Step-by-step explanation:
Formula for perimeter of triangle:
P = a + b + c
where a, b and c are the sides of the triangle.
Assuming the triangle is equilateral, all sides would be equal,
a = b = c = x
⇒ P = x + x + x
<u>∴ 20 = 3x.</u>
