Question

find the length of the third side of a right triangle given the measurement of the other two sides.

7. 6 cm, 8 cm (1 point)

9 cm
7 cm
10 cm
11 cm

Answer 1

do they tell you which sides they are?

Answer 2

i mean are they the two shorter sides?

Answer 3

no

Answer 4

10..

Answer 5

all options are larger than 6 and 8 already..

Answer 6

ok then this will be a bit longer:

so we know that either 8 will be our longest side, or that we need to find the hypotenuse:

so if we assume that 8 is the longest side, then we can use pythagoras' thm to calculate the other short side:

c^2=a^2+b^2
64= 36+b^2
b^2=28
b=sqrt(28)

seeing as thats not one of our answers, we know now that 6 and 8 are the 2 shorter sides:

so we set up pythagoras again:

c^2=36+64
c^2=100
c=10
this is one our answers, so we know its right

Answer 7

@cinar one of the options was 7, which meant that 8 could have been the biggest side, so we had to check and make sure that it wasn't

Answer 8

I did not noticed that..

6,8,10 special right triangle..
