Determine the third side measure that will form a right triangle if two of the sides are 7 and 24?

OpenStudy (dumbcow):

which side is the hypotenuse?

OpenStudy (anonymous):

A 25 B 27 C does not exist D 40

OpenStudy (dumbcow):

\[a^{2} +b^{2} = c^{2}\] where c is the hypotenuse

OpenStudy (dumbcow):

ok then im assuming we are solving for the hypotenuse, c plug in 7 and 24 as a and b

OpenStudy (anonymous):

25

OpenStudy (anonymous):

right????

OpenStudy (anonymous):

IDK! :'(

OpenStudy (dumbcow):

ok have you tried substituting 7 and 24 into the formula and solving for c

OpenStudy (dumbcow):

\[c^{2} = 7^{2} + 24^{2}\]

OpenStudy (anonymous):

so it's 25?

OpenStudy (dumbcow):

yep good job

OpenStudy (anonymous):

thanks

OpenStudy (dumbcow):

use that for any right triangle, just remember c is the hypotenuse or longest side
