Question

If sinα=1/2, then the value of (tanα + cotα)2 is. (a)16/3 (b) 8/3 (c) 4/3 (d)10/3

Answer 1

( c) 4/3

sin alpa = 1/2

sin alps = 30°

  

hope this will help u

Answer 2

H²=B²+P²

(2)²=(B)²+(1)²

4=(B)²+1

4-1=(B)²

3=(B)²

=√3

TANA=P/H

COTA=H/P

(TANA+COTA)²=(1/√3*2/√3)²=

=(4/√3)²=16/3

ANSWER=16/3
