Odpowiedź:
a =2 x + 4 x = 6 x
( 2 x )² + h² = ( 6 x)²
h² = 36 x² - 4 x² = 32 x² = 16*2*x²
h = 4√2 x
sin α = [tex]\frac{h}{a} = \frac{4\sqrt{2} x}{6 x} = \frac{2\sqrt{2} }{3}[/tex] ≈ 0,9428
α ≈ 70°30'
=============
β ≈ 109°30'
Szczegółowe wyjaśnienie:
" Life is not a problem to be solved but a reality to be experienced! "
