Answer 1

Step-by-step explanation:

we know that a complete angle is 180° so to get inner sides I am going to subtract 9x from 180

6x-180°+9x-180°+9x=180° (angle sum property)

18x+6x-360°=180°

24x=180°+360°

24x=540°

x=540/24

x=22.5

HOPE IT HELPS YOU

Answer 2

Answer:

x = 15

Step-by-step explanation:

let the unknown angle inside the triangle is 180-9x

sum of the angles of triangle is 180°.

so (180-9x) + (180-9x) + 6x = 180.

Further solving gives x = 15°
