What is the height of an equilateral triangle with side lengths of 14?

<span>So it's length would be half of the length of the base </span>\frac{14}{2} = 7 <span>=> </span>7^{2} + x^{2} = 14^{2} => 49 +  = 196 => x^2 = 147 => x = sqrt 147 = 7 * sqrt 3 . So the altitude is equal to 7 * sqrt 3. An approximate value to that would be 12.12

Hope this helps

I need help with this and I don’t understand it

Lets break it down:

The bottom right picture shows an approximation of what 1 wingspan length is, and the goal is to <u>estimate </u>lengths.

A. 1 wing is approx. 7 meters. To find the wingspan of the plane just do 7 meters multiplied by 2 = 14 meters (approx wingspan). Now we convert (remember, to the nearest foot!)

14 meters = 45.93 ft

Round it to the nearest foot = 46 ft is your approx. wingspan.

B. The height. This is one is a little tricky! Lets try to use what we know:

1 wing is approx. 7 meters. Since these are approximations, lets say half of one wing is <u>roughly</u> the size of the height of the plane. Since these are approximations I'd say 4 meters.

4 meters = 13 ft (rounded).

<em>I checked online for the specs of the Lysander and the exact height is 14 ft 6 in and wingspan is 50 ft. </em>This means our approximations were correct!

C. The length would be 10 ft + 7 meters

10 ft = 3 meters (rounded)

3 meters + 7 meters = 10 meters

<em>(converting to meters then to ft at the end because it's less messy)</em>

10 meters = 33 ft (rouned)

length of the Lysander is approx. 33 ft!

(the real length is 30 ft 6 in)

This means our approximations were correct once more.

Hopefully this helped you and made your night/day easier.

Sam makes $400 per week plus $20 commission on each new cell phone plan she sells. Write an equation and solve it to determine h
Sergio [31]
The equation would be 400+20c per week so if you do that equation, to figure it out 680-400=280 and then you would divide it by 20 and whatever that answer is, in this case it would be 14.
