Question

If a right triangle has legs of lengths a and b, then the length of its hypotenuse can be found using the expression √a^2 + b^2. Find the length of the hypotenuse of a right triangle whose legs measure 11cm and 14cm. Round your answer to the nearest tenth

Answer 1

you can also use a^2+b^2=c^2

11^2+14+2=c^2
121+196=c^2
317=c^2
√317=c
17.8=c

Answer 2

=17.8
