Find the value of this variable A 146 degree B 73 degree C 84 degree D 62 degree Help

Answer :

Answer: B. 73 degree

Step-by-step explanation:

We know that a triangle has 180 degree

62 + 84 = 146 degree

180 - 146 = 34 degree

34 degrees is the angle inside the triangle. The inside angle must add with the outside angle = 180 degree

So the outside angle is

2x = 146

x = 73
