Given that
AB=12 cm
AC=13cm
B=90°
So,BC power 2=ACpower2-AB power2
=13 power2-12power2
=5
So BC=5
Now,tanA =p/b
=5/12
cotC =b/p
5/12
So tanA+cotC=5/12+5/12 =10/12 = 5/6.
AB=12 cm
AC=13cm
B=90°
So,BC power 2=ACpower2-AB power2
=13 power2-12power2
=5
So BC=5
Now,tanA =p/b
=5/12
cotC =b/p
5/12
So tanA+cotC=5/12+5/12 =10/12 = 5/6.
