Question
The value of x is
- 7
- 9
- -11
- -6
Hint:
Applying the sum of angles in a triangle is 180° . find the value of x by solving the equation .
The correct answer is: -11
From the above triangle ,
(x+62)° + 74° + 55° = 180° (sum of angles in a triangle)
x + 191° = 180°
x = 180° - 191° = -11°
Therefore, Value of x is -11°.

The measure of the missing angle is
¶A triangle has three angles or sides, and the sum of the angles or sides is always 180 degrees, the missing angle in the triangle's measurement is found by first taking the sum of the other two angles and then subtracting that number from 180.
Exterior Angle of Triangle Properties
The exterior angles of a triangle have three fundamental properties.
• In a triangle, every exterior angle and corresponding interior angle create a linear pair of angles. So, the interior and exterior angles add up to 180°.
• A triangle's exterior angle equals the sum of its two opposite interior angles (remote interior angles). The Exterior Angle Theorem is another name for this.
• The sum of the exterior angle of a triangle is 360°.
