Question

calculate the value of x in each of the following figure

Answer 1

the interior angle of angle a =180°-110°=70°
the interior angle of angle b=180°-120°=60°
the sum of the angles of a triangle is 180°
70°+60°+x°=180°
130°+x°=180°
x°=50°
therefore x =50°.

hope it helps

Answer 2

The answer is 50°

Explanation:

Interior angle - The angle created between two adjacent sides of a triangle is referred to as the interior angle.

Exterior angle - The angle produced between a triangle's side and a neighboring side that extends outward is referred to as the exterior angle.

Angle sum property of triangle states that for ∆ABC,

The triangle's interior angles add up to 180°.

Solution:

Interior angle A = 180° - 110° = 70°

Interior angle B = 180° - 120° = 60°

The sum of the angles of a triangle is 180°

70° + 60° + x° = 180°

130° + x° = 180°

x° = 50°

Therefore x = 50°
