Question

if cosec Q = 2/1, show that cot Q + sinQ/ 1+cosQ=2​

Answer 1

Answer:

Step-by-step explanation:

Given cosec Q =2

Cosec Q =2=H/P

Using Pythagoras theorem

B=√P-H

B= √(2)^2-(1)^2

B = √ 4-1

B =√3

Cot + sin/1+cos=2

√3+1/2=√3+1/2/2+√3/2

1+√3/2

√3+1/2+√3

2√3+3+1 / 2+√3

2√3+4 / 2+√3

2(√3+2) / 2+√3

√3+2 cansalout

It left only 2

Hence the answer of this question is 2
