Answer 2

Answer:

(tanA +secA)²=4

Step-by-step explanation:

sinA=3/5- - - 1

sinA=perpendicular/hypotenuse- -2

on comparing 1&2 we get

perpendicular=3

hypotenuse=5

now using Pythagoras theorem we get

base=4

tanA=perpendicular/base

=3/4

secA=hypotenuse/base

=5/4

(tanA +secA)²

=[(3/4)+(5/4)]²

=(8/4)²

=2²

=4
