Answer:
82.4 cm
Step-by-step explanation:
The computation of the height is given below:
As we know that each right triangle contains the top angle of 20 degrees
So, the right angle & the bottom corner angle equivalent to
= 180 - 90 - 20
= 70 degrees
Now the height is
tangent = opposite leg ÷ adjacent leg
tan (70°) = height ÷ 30 cm
height = 30 cm × tan (70°)
= 82.4 cm

Step-by-step explanation:

Im so sorry.. I did not mean to submit an answer..
And I honestly don't know how to get rid of my answer.. but I will try to help.
4x²- 20x=0 =
= -√5,
= √5
3x²-42=0 =
= -√14,
= √14
2x²-14x=0 =
= 0,
= 7
8x²-98=0 =
= -
,
= 
I hope that these are the answers that you wanted, if they are not, I am sorry, tell me and I will try to fix them.
Consider a few powers which are close to 120 and 130:
squares:

cubes:

4th powers:

now clearly there is no point of checking 5th, 6th and so on powers of numbers >2.
so check powers of 2:

So we have :
