Answer:
The missing angle are: 123°, 65°
5x+10° = 65°
11x +2° = 123°
Explanation:
11x+2° = 5x+10°+58° {the exterior angle formed by producing the side of triangle is equal to two non adjacent angle}
or, 11x - 5x = 58°+10°-2°
or, 6x = 66°
or, x = 66°/6
or, x = 11°
therefore, x = 11°
11x+2° = 11×11°+2°
= 121°+2°
= 123°
5x+10° = 5×11°+10°
= 55°+10°
= 65°
I hope it helped u :)
