this is what i have: X= 6+(90-X)+2(90-X) and i got 42 degrees?
If the angles A, B and C forms a triangle, then angle A is 111 degrees.
Each exterior angle is 360/42 = 8.571429 degrees So each interior angle is 180 - 8.571429 = 171.4286 degrees.
96˚all angles to a triangle equals 180˚

42 degrees
It is: 180-42 = 138 degrees
21 degrees
The vertex angle of an isosceles triangle is equal to the measure of each of its base angles. Therefore, if one of the base angles measures 42 degrees, then the vertex angle also measures 42 degrees.

8.57 degrees
If the angles A, B and C forms a triangle, then angle A is 111 degrees.
32 degrees
69 degrees 180-42 = 138 138/2 = 69 degrees You do not need the measure of the side to derive the answer.
Each exterior angle is 360/42 = 8.571429 degrees So each interior angle is 180 - 8.571429 = 171.4286 degrees.
The 42 interior angles of a regular 42-agon add up to 7200 degrees and each angle is 7200/42 which is 171.'428571' degrees recurring decimal '428571'
