Question

calcule o valor de x ou y utilizando o teorema de Pitágoras

Answer 1

b) (x)²+ (12)² = (15)²
x² = 225 - 144
x² = 81
x = √81
x = 9
-------------------
e) (12)² + (15)² = x²
144 + 225 = x²
369 = x²
x = √369
x = √3*3*41
x = 3√41
-------------------
c) (x)² + (6)² = (8)²
x² = 64 - 36
x² = 28
x = √2*2*7
x = 2√7
-------------------
f) (x)² + (15)² = (25)²
x² = 625 - 225
x² = √400
x = 20
-------------------
g) (3)² + (4)² = (x)²
9 + 16 = x²
x² = 25
x = √25
x = 5
