Question

Calcular la medida del lado faltante en cada uno de los siguientes triangulos rectangulos​

Answer 1

Explanation:

In this case, we will use Pythagoras theorem for all three cases.

Pythagoras theorem : Hypotenuse² = base² +perpendicular²

(1) a = 5, b = 12

`c=\text{Hypotenuse}\\\\c=√(a^2+b^2) \\\\x=√(12^2+5^2) \\\\x=13`

(2) b = 30, c = 34

`a=√(c^2-b^2) \\\\a=√((34)^2-(30)^2) \\\\a=16`

(3) b = 15, c = 25

`a^2=√(c^2-b^2) \\\\a=√((25)^2-(15)^2) \\\\a=20`

Hence, this is the required solution.
