(The photo is too big to fit so don't mind that.)

Calculate the value of c in the triangle below.

Answer 1

82

Explanation:

1'st step:
`a^(2)` +
`b^(2)`=
`c^(2)` is the formula for the pythagorean theorem

2'nd step :
`18^(2)` +
`80^(2)` =
`c^(2)`

3'rd step: 324+6400 =
`c^(2)`

4'rd step: 6724=
`c^(2)`

5'th step:
`√(6724)` =82

6'th step : therefore the value of c is 82 cm
