Question

calcule a medida x:​

Answer 1

Resposta:

a)

$\sf PA \cdot PB = PC \cdot PD$

$\sf 6 \cdot 4 = x \cdot 3$

$\sf 3x = 24$

$\sf x = \dfrac{24}{3}$

$\boxed{ \boxed { \boldsymbol{ \sf \displaystyle x = 8 }}} \quad \gets \mathbf{ Resposta }$

b)

$\sf PA \cdot PB = PC \cdot PD$

$\sf 9 \cdot 8 = 2x \cdot x$

$\sf 2x^{2} = 72$

$\sf x^{2} = \dfrac{72}{2}$

$\sf x^{2} = 36$

$\sf x = \sqrt{36}$

$\boxed{ \boxed { \boldsymbol{ \sf \displaystyle x = 6 }}} \quad \gets \mathbf{ Resposta }$
