A 30 feet ladder is leaning against the wall. The top of the ladder is resting 25 feet on the building. How far is the base of t
g100num [7]

Answer:

16.58 feet

Step-by-step explanation:

a² + b² = c²

Think of this as a right triangle

The hypotenuse is 30, and one of the legs is 25

To find the other leg, subtract the square of the hypotenuse by the square of the given leg

30² - 25² = leg

900 - 625 = 275

Square root the answer to find the length of the missing leg

√275 = 16.583123951777

The leg is 16.58 ft.

How to calculate the percentage?
miv72 [106K]

\:  \:  \:  \:  \:

  1. <u>How to calculate percentage of a number. Use the percentage formula: P% * X = Y</u>

  1. <u>Convert the problem to an equation using the percentage formula: P% * X = Y.</u>
  2. <u>P is 10%, X is 150, so the equation is 10% * 150 = Y.</u>
  3. <u>Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.</u>

  • <u>Multiply by 100 and add a percentage </u><u>sign</u>
  • <u>0.876 = 0.876 * 100 = 87.6%</u>

What is the Pythagorean triple generator and how does it work?​
r-ruslan [8.4K]

Answer:

Step-by-step explanation:

The Pythagorean Theorem states that

a^2+b^2=c^2

or that the two legs added together squared equal the hypotenuse squared

not: this only works with right triangles

Now Pythagorean triples are the set of sides that follow that rule

an example would be 3,4,5

why is it a Pythagorean triple?

well because it follows

a^2+b^2=c^2

3^2=9\\4^2=16\\16+9=25\\5^2=25

25=25
