Respuesta :

Answer:

The answer would be 19

Step-by-step explanation:

Using pythagoras theorem

15+6= 21

a^2+b^2= c^2

In this scenario,

c^2-a^2= b^2

Meaning it would be 21^2+8^2

= 377

Square root of 377 would be 19.416

?= 19.416

The missing side length of the right angle triangle is 20

How to solve missing sides using Pythagoras theorem

Pythagoras theorem States that the square of the longest side of a triangle is equal to the sum of the square of the opposite side and no square of the adjacent side.

  1. The diagram is a right angle triangle with sides AB, BC and CA.

  • The longest side is BC

BC² = AB² + CA²

(15 + 6)² = x² + 8²

21² = x² + 8²

21² - 8² = x²

441 - 64 = x²

377 = x²

  • find the square root of both sides

x = √377

x = 19.41648783894759891856148511263886343

Approximately to the nearest whole number

= 20
