Question

the angal of a quadrilateral are 90०,80०and 125० and x ०. find the value of x​

Answer 1

Answer:

$65 \degree$

Step-by-step explanation:

$\boxed{ 90 \degree+ 80 \degree + \: \degree125 + \angle \: x = 360 \degree \: \: \: \: \: \: \: \: \: \: \: \: \: \: (angle \: sum \: property \: of \: a \: quadrilateral)}$

$\boxed{\angle 295 \degree + \angle \: x = 360 \degree}$

$\boxed{\angle \: x = 360 \degree -295 \degree}$

$\boxed{\angle \: x = 65 \degree}$

Answer 2

sum of quadrilateral = 360

90 + 80 + 125 + x = 360

295 + x = 360

x = 65
