Question

Three angles of quadrilateral are 60degree,80 degree ,150 degree forth is answer

Answer 1

Given:

• First angle of quadrilateral = 60°
• Second angle of quadrilateral = 80°
• Third angle of quadrilateral = 150°

_____________________

To find:

• The fourth angle of the quadrilateral.

_____________________

Solution:

☆ We know that sum of all the angles of a quadrilateral is 360°. So,

Let the fourth angle be 'x'.

60° + 80° + 150° + x = 360°

290° + x = 360°

x = 360° - 290°

$\boxed {\mathfrak {\orange {x=70 \degree}}}$

Verification:

Substitute the value of 'x' as 70° in the equation,

60° + 80° + 150° + x = 360°

60° + 80° + 150° + 70° = 360°

360° = 360°

LHS = RHS

Hence Verified!
