Respuesta :

Equilateral triangle total angle is 180
So
46+61+third angle = 180
46+61-180 = third angle
107-180= 73

Answer: 73°

Step-by-Step Explanation:

Let the 3rd Angle be ‘x’

By Angle Sum Property of a Triangle, the Sum of all Angles of a Triangle = 180°

1st Angle = 46°
2nd Angle = 61°
3rd Angle = x°

Therefore,
46 + 61 + x = 180
107 + x = 180
x = 180 - 107
=> x = 73

Therefore,
3rd Angle = 73°
