8.4 * 10^1 is what I think the answer is
The bottom left angle is 180 -80=(100)
So the remaining 2 angles are equal 80
As all angles in a triangle are equal to 180
X+5 + x - 5 =80
Simplify
2x=80
X=40
Soo one of the angles are 40-5 which is (35)
And the other is 40+5 which is (45)
So sean is not correct
~sorry sean teehee
2.18 that will be ur answer
It would be 1 fjjffjdj fifth because the ending would replace the 8
