PLEASE I need help on these 4 problems you don’t have to do them all but if you can at least do one of them TYSM

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

Hope it helps.
