its a 2 step process that uses pythagoras' theorem... 

in the larger triangle you have a hypotenuse of 17 and base of 8

and you need to find the shorter side

can you do that..?

campbell_st · Answer

leave the answer for the shorter side or height  as a radical 

then the smaller triangle, you need to find the hypotenuse x 

you just found the height, and the base is 5
