Question

If in a triangle,Sin A=3/4,evaluate CosA,SecA,TanA,and CosecA?

Answer 1

Answer:

Hiii

Step-by-step explanation:

SinA=3/4

SinA can be written as perpendicular/hypotenuse

SinA=p/h=3/4

Here, hypotenuse=4 perpendicular=3

Using pythagorus theorm

(Hypotenuse)²=(base)² + (perpendicular)²

(4)²=(base)²+(3)²

16=(base)²+ 9

16-9=(base)²

7=(base)²

base=root7

CosA=base/hypotenuse

=root7/4

SecA=1/cosA

=1/root7/4

=4/root7

TanA=perpendicular/base

=3/root7

CosecA=1/sinA

=1/3/4

=4/3

This is ur answer
