A) x+12+90=180
x+102=180
x=180-102
x=78
Usaremos teorema de Pitágoras;
C² + C² = H²
1)
5² + 12²= X²
25 + 144 = X²
169 = X²
2)
80² + Y² = 100²
6400 + Y² = 10000
Y² = 3600

Verified answer
Usaremos teorema de Pitágoras;
C² + C² = H²
1)
5² + 12²= X²
25 + 144 = X²
169 = X²
X = 13
2)
80² + Y² = 100²
6400 + Y² = 10000
Y² = 3600
Y = 60
