Question

xyz is a triangle,right angled at z,if xy=13cm and xz = 5cm, find yz
​

Answer 1

Step-by-step explanation:

since tr. XYZ is a rt. angled tr.

therefore, we apply pythagores theorem

now,

(XY)/\2= (ZY)/\2+(XZ)/\2

=>(13)/\2=(ZY)/\2+(5)/\2

=>169=25+(ZY)/\2

=>169-25=(ZY)/\2

=>144=(ZY)/\2

=>ZY=12
