Answer:
See the second attachment for long division by hand. The first attachment shows the "work" I would usually do.
Step-by-step explanation:
In college math, you are generally expected to be able to make use of a scientific and/or graphing calculator. Division is one of the simpler operations these devices can perform.
If you are doing long division by hand, use the method you were taught in 3rd or 4th grade. The one shown is one of several different methods being taught now.
Answer:
For right angle triangle,
we use Pythagoras theorem that is:
c =
For question 1:
c = ?
a = 40
b = 9
putting them in formula,
c =
c = 41
For question 2:
c = ?
a = 12
b = 13
putting them in formula,
c =
c = approximately 17.69181
For question 3:
c = 35
a = 20
b = ?
putting them in formula,
1225 = 400 +
= 1225 - 400
= 825
b = 5
For question 4:
c = 37
a = 20
b = ?
putting them in formula,
1369 = 400 +
= 1369 - 400
= 969
Taking square root on both sides
b = 31.12
