if 4 tan a =3 evaluate 4sina-3cosa/4sina+2cosa
Answers
Step-by-step explanation:
4tan a= 3
=> tan a=3/4
=>p/b=3/4
=>p =3,b=4, h=√p²+b²
=√3²+4²
=5
sin a=p/h =3/5
cos a=b/h=4/5
4sin a -3cos a /4sin a +2cos a
=4*(3/5) -3*(4/5)/4*(3/5)+2*(4/5)
=(12/5)-(12/5)/(12/5)+(8/5)
=(12/5)-1+(8/5)
=(12-8)/5-1
=4/5-1
=-1/5
The value of is 3.
Step-by-step explanation:
Given:
If
To Find:
The value of .
Solution:
As given,If
p/b=3/4
p =3,b=4, h=√p²+b²
h=√3²+4²=5
The value of
Thus,The value of is 3.
