Proszeee o pomoccc jak niby powierzecie to bedziecie miec ladby widok !! PRoszeee niech ktos to zrobi ..
zad. 1
|AG|²+|GW|² = |AW|²
(x+1)² + x² = y²
x² + 2x + 1 + x² = y²
2x² + 2x + 1 = y²
zad. 2
3² + |CB|² = (√13)²
9 + |CB|² = 13
|CB|² = 13-9
|CB|² = 4
|CB| = 2
9² + 7² = x²
81+49=x²
130=x²
x = √130
zad. 3
10² = x² + (2√10)²
100 = x² + 40
x² = 100 - 40
x² = 60
x = 2√15
P= 1/2 * 2√10 * 2√15
P = √10 * 2√15
P = 2√15*10
P= 2√150
P= 10√6 j²
