Answer 1

Answer:

in triangle abc if angle b is equal to 90° ab is equal to 12 cm and BC is equal to 5 cm then the value of tan a is

Answer 2

Answer:

AB=12cm

BC=5cm

then,

AC=?

by phytagarous theorem

AC²=AB²+BC²

AC²=(12)²+(5)²

AC²=144+25

AC=√(169)

AC=13 cm

tan a=perpendicular/base

tan a =P/B

tan a =5/12
