In order to find scientific notation you have to move the decimal (which is located at the end of the number in the case) where it becomes a number less than 10 but greater than 1.
(190,000.) = (1.9)
How ever many times you moved the decimal (in this case 5) will now become the exponent (whether the exponent is positive or negative will tell you whether to move left or right)
(1.90,000.)
(5)
As an end result 190,000 in scientific notation will then equal 1.9x10^5
(190,000.) = (1.9)

Remember
the exterior angle=sum of the other 2 interior anlges
therfor
(one that is less pointy triangle)
2x+3x=135
5x=135
x=27
2*27=54
3*27=81
the interior angles are 54 and 81 and x=27
other pointier one with 3x-1 on it
12+3x-1=167
11+3x=167
minus 11
3x=156
divide 3
x=52
sub
3*52=156
156-1=155
missin angle is 155, x=52
