Think of one leg of a right triangle is 21' and the length of the hypothenuse is 29' what is the length of the other leg
Ksivusya [100]

Answer:

length of other leg = 20'

Step-by-step explanation:

Given:

One leg of triangle let it be base of triangle = 21'

Hypotenuse = 29'

To Find:

Third leg =perpendicular = ?

Solution:

Given is a right angled triangle with two of its sides given to us

We have Pythagoras theorem for right angled triangle and according to it

Pythagoras theorem is

for a right angled triangle

(hyp) ² = (perp)²+(base)²

We have the values of hyp and base

putting them in the equation we get

(29) ² = (perp) ²+(21) ²

841 = (perp) ² + 441

subtracting 441 from both sides we get

841 - 441 = (perp) ² + 441 - 441

400 =  (perp)²

or

(perp) ²=400

Taking square root of both sides

\sqrt{(perp)^{2} }=\sqrt{400}

it gives us

perp = ± 20'

As it is length and it can not be negative so

perp = 20'

or

length of other leg = 20'

A crew of loggers cleared ½ acre of lumber in 4 days. How long will it take the same crew to clear 2 ¾ acres of lumber?
Tanzania [10]
You can use a proportion

1/2(acres)       2(3/4)acres
--------------  =   --------------
4(days)              x(days)

4*2(3/4) = 6
6/(1/2) = 12

It would take 12 days.

Hope this helped☺☺
