Question

. From the following figure find 'x' value. 80° (4x - 10)​

Answer 1

Step-by-step explanation:

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°.
