2. A guy wire for a tree is 20 ft. long, making a 21o angle with the ground. How far is the base of the tree from a stake anchor

Alenkasestr [34]

Answer:

the base of the tree from a stake anchoring the wire is 18.7 ft long

Step-by-step explanation:

A guy wire for a tree is 20 ft. long, making a 21 degree angle with the ground.

It forms a right angle triangle. the hypotenuse of the triangle is 20 ft

The adjacent side of the given angle 21 degree is the base of the tree from a stake

Let x be the base length

$cos(theta)=\frac{adjacent}{hypotenuse}$

$cos(21)=\frac{x}{20}$

$20cos(21)=x$

$x=18.7$

the base of the tree from a stake anchoring the wire is 18.7 ft long
