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


hypotenuse = 7.3

Step-by-step 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

= c

7.3 = c

if you can mark me brainlist

60 + 20 + 12=92

so, 100-92 is 8

therefore 8 are in neither the band nor the orchestra
