The missing value of the given triangle would be = 70°
How to calculate the missing value of the triangle?
To determine the missing value of the triangle, the following steps should be taken as follows:
The given exterior angle = 110°
But the angle on a straight line = 180°
Hence the value of y would be = 180-110 = 70⁰
Therefore, the measurement of angle y° would be = 70°
