# Right Δ

A right triangle has the length of one leg 7 cm and length of the hypotenuse 25 cm. Calculate the height of the triangle.

Result

vc =  6.7 cm

#### Solution:

$a = 7 \ cm \ \\ c = 25 \ cm \ \\ b = \sqrt{ c^2-a^2 } = 24 \ cm \ \\ \ \\ S = S \ \\ \dfrac{1}{2} c v_c = \dfrac{1}{2} a b \ \\ c v_c = a b \ \\ c v_c = a v_c = \dfrac{a}{c} b = \dfrac{ 7}{ 25} \cdot 24 = 6.7 \ \text { cm }$
