Question

Need help with this. its very hard and i dont know what to do and my work is due at 11:59 pm today .

Answer 1

125°

Explanation:

Sum of all the internal angles in a triangle is 180°

So, we have,

67°+58°+ Adjacent angle of 1 = 180°

125°+Adjacent angle of 1 = 180°

Adjacent angle of 1 = 180° - 125° = 55°

Angle 1 and its adjacent angle are supplementary

So, Angle 1 + Adjacent angle of 1 = 180°

Angle 1 + 55° = 180°

Angle 1 = 180° - 55° = 125°
