Question

2cosA = 1 then find the value of cosecA and SinA.​

Answer 1

Answer:

cosecA=2/√3

sinA=√3/2

Explanation:

CosA=1/2=Base/perpendicular

therefore, H²=B²+P². [by Pythagoras theorem]

since, base=1, perpendicular=2

so, P²=2²-1²=4-1=3

so, P=√3

sinA=Perpendicular/Hypotenuse=√3/2

cosec= 1/SinA=2/√3
