Step-by-step explanation:
by using the pythagoras theorem,
the height of the ladder touching the wall =
√(20²- 4²)
=√ (400-16)
=√384
= 8√6 feet
or 19.6 feet
The answer is 34,020. I hope that this helps.
The sum of the 3 angles in a triangle needs to be 180.
To find the 3rd angle subtract the two k own angles from 180
3rd angle = 180 - 41 -5 = 134 degrees
The answer is 63 add 50and 10 which is 60 then 3 from the left over of thirteen which is 63 :)
