Question

The angle of a quadrilateral are 90 degree 80 degree 125 degree find the X value

Answer : Value of x is 65°.

Given:-

• Angles of quadrilateral are 90°, 80°, 125° and x°.

To find:-

• Value of x.

Solution:-

We know,

Sum of all interior angles of quadrilateral is 360°

So,

⟶ 90° + 80° + 125° + x° = 360°

⟶ 295° + x° = 360°

⟶ x° = 360° - 295°

⟶$\LARGE \fbox\blue{ x = 65° }$

Verification:-

⟶ 90° + 80° + 125° + x° = 360°

Put x = 65°

⟶ 90° + 80° + 125° + 65° = 360°

⟶ 295° + 65° = 360°

⟶ 360° = 360°

$\Large\fbox\red{Hence\: Proved}$

Therefore, Value of x is 65°.
