Question

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

Answer 1

For right angle triangle,

we use Pythagoras theorem that is:

`c^(2) =a^(2) +b^(2)`

c =
`\sqrt{a^(2) +b^(2) }`

For question 1:

c = ?

a = 40

b = 9

putting them in formula,

c =
`\sqrt{40^(2) + 9^(2) }`

c = 41

For question 2:

c = ?

a = 12

b = 13

putting them in formula,

c =
`\sqrt{12^(2) + 13^(2) }`

c = approximately 17.69181

For question 3:

c = 35

a = 20

b = ?

putting them in formula,

`c^(2) =a^(2) +b^(2)`

`35^(2) = 20^(2) + b^(2)`

1225 = 400 +
`b^(2)`

`b^(2)` = 1225 - 400

`b^(2)` = 825

`\sqrt{b^(2) } = √(825)`

b = 5
`√(33)`

For question 4:

c = 37

a = 20

b = ?

putting them in formula,

`c^(2) =a^(2) +b^(2)`

`37^(2) = 20^(2) + b^(2)`

1369 = 400 +
`b^(2)`

`b^(2)` = 1369 - 400

`b^(2)` = 969

Taking square root on both sides

b = 31.12

Hope it helps.
