- 112o
- 75o
- 143o
- 149o
Hint:
the sum of all the interior angles of a triangle is always 180
The correct answer is: 75o
the sum of all the interior angles of a triangle is always 180
We know that;
angle a= 68 and angle b=37
angle a +angle b +angle c=180
68+37+angle c=180
angle c+105=180
angle c=180-105
angle c=75
