Question

Find the length of the hypotenuse to the nearest tenth. (example 4.5)
7
2


Answer 1

hypotenuse = 7.3

Explanation:

the length two legs of the given triangle are 7 and 2 respectively.

using pythagoras theorem

a^2 + b^2 = c^2

7^2 + 2^2 = c^2

49 + 4 = c^2

53 = c^2

`√(53)` = c

7.3 = c
