If sinA=34 , calculate secA?
Computing the required values:
Given:
sinA=34→1
We know, by sin definition;
sinA=PH=34→2
By comparing equation 1 and 2, we have
Perpendicular P=3, and Hypotenuse H=4
On using Pythagoras theorem in △ABC.
H2=P2+B2⇒B2=42-32⇒B=7
Hence, Base B=7.
By definition,
secA=HB⇒secA=47
Hence, the required value is 47.
