Question

5. Determine o valor de X em cada figura:​

Answer 1

Explicação passo-a-passo:

a)

$\bf{60 + 60 + x = 180}$

$\bf{120 + x = 180}$

$\bf{x = 180 - 120}$

$\boxed{ \bf{x = 60}}$

b)

$\bf{30 + 90 + x = 180}$

$\bf{120 + x = 180}$

$\bf{x = 180 - 120}$

$\boxed{ \bf{x = 60}}$

c)

$\bf{90 + 90 + x + x = 360}$

$\bf{180 + 2x = 360}$

$\bf{2x = 360 - 180}$

$\bf{2x = 180}$

$\bf{x = \frac{180}{2} }$

$\boxed{ \bf{x = 90}}$

d)

$\bf{x + x + x + x = 360}$

$\bf{4x = 360}$

$\bf{x = \frac{360}{4} }$

$\boxed{ \bf{x = 90}}$
