Find the value of X

Answer 1

The value of x is 155° .

Sum of all the angles on a line is 180°.

Sum of all the interior angles of a triangle is 180°.

Answer 2

x = 155°

Explanation:

most left upper angle = 180° - 35° - 90° = 55°

inner middle top angle = 180° - 60° - 55° = 65°

inner middle has right angle, that is 90°

inner middle bottom angle is then, 180 - 90° - 65° = 25°

then as x lies on a straight line with 25°

x + 25° = 180°

x = 180° - 25°

x = 155°
