a guy wire for a tree is 20 ft long, making a 21 angle with the ground. How far is the base of the tree from a stake anchoring t

evablogger [386]

Answer:

18.7 feet far

Step-by-step explanation:

Based on the information given we can conclude that our set up will be a Right triangle (i.e. one angle is 90°), where the hypotenuse will be denoted by the guy wire of $20ft$ and angle of 21° is the angle formed between then hypotenuse and the base (i.e. ground).

Thus we want to find the base length (lets call it $x$ ) of this triangle, so we can use trigonometry as we have one angle and the hypotenuse, as follow:

$cos(21)=\frac{adjacent side}{hypotenuse}=\frac{baselength}{guywire}\\\\ cos(21)=\frac{x}{20} \\x=20cos(21)\\x=18.671\\x=18.7ft$

So the base is approximately 18.7 feet far from the tree of the anchored wire.

[find the area please explain steps]

Length of base of the top triangle = 23 inches

Length of height of the top triangle = 47 inches

Area of the top triangle :

$= \frac{1}{2} \: \times \: base \: \times \: height$

$= \frac{1}{2} \times 23 \times 47$

$= \frac{1}{2} \times 1081$

$= \frac{1081}{2}$

$= \color{hotpink} \: 540.5 \: \:sq. inches \:$

Thus, area of the top triangle = 540.5 sq.inches

Length of base of the bottom triangle = 47 inches

Length of height of the bottom triangle = 46 inches

Area of the bottom triangle :

$= \frac{1}{2} \: \times \: base \: \times height$

$= \frac{1}{2} \times 47 \times 46$

$= \frac{1}{2} \times 2162$

$= \color{hotpink}1081 \:sq. inches$

Area of the bottom triangle = 1081 sq.inches

Area of the total figure :

= Area of top triangle + Area of bottom triangle

$= 540.5 + 1081$

$= \color{hotpink}\bold{1621.5 \: \: sq.inches}$

Therefore, the area of the figure = 1621.5 sq.inches
