Question

Calcule o valor de c, r x e y do triângulo abaixo

Answer 1

1°) r² = ($\sqrt{7}$)² + (3$\sqrt{2}$)²
r² = 7 + 18
r² = 25
r = $\sqrt{25}$
r = 5

2°) $\sqrt{7} . 3 \sqrt{2}$ = c . 5
5c = 3.$\sqrt{14}$
c = $\frac{3. \sqrt{14} }{5}$

3°) ($\sqrt{7}$)² = 5 . x
5x = 7
x = 7/5

4°) (3$\sqrt{2}$)² = 5 . y
5y = 18
y = 18/5
