Answer:24
Step-by-step explanation: i found the answer using the pythogaras theorem,the formula used is, h squared=b squared +p squared,formula used to find missing legnths of triangles such as hypotaneous and height.in this question you have to find the height,as you can see to the opposite of hypotaneous its height/perpendicular.
so according to formula,h squared=b squared+p squared
so,26 squared=10 squared+p squared.
in order to find p
p squared=26 squared -10 squared
which gives us 576
and p squared =576
the square on the p will go on the other side and become an underroot.
take the underoot of 576
which gives us p=24.
so the legnth is 24, found using pythogares theorem.by rearranging the formula and making p the subject in the formula
