Question

What is the value of m in the figure below?

( Picture attached below )

Answer 1

Hint: find the altitude first, then use this altitude to find the value of m

Answer 2

Would that be 77?

Answer 3

the altitude is actually sqrt(77), but you're very close

Answer 4

now use the pythagorean theorem

a^2 + b^2 = c^2

( sqrt(77) )^2 + 7^2 = m^2

m^2 =77 + 49

keep going to solve for m

Answer 5

sqrt(126)? Is that correct?

Answer 6

yep

Answer 7

m = sqrt(126)

Answer 8

Awesome! Thanks I really appreciate it!!
