Answer 1

Answer:

Hope it is helpful to you

Step-by-step explanation:

Given that:

Given that:secθ= 5 / 4

Given that:secθ= 5 / 4We need to find the value of cosθ

Given that:secθ= 5 / 4We need to find the value of cosθAccording to trignometric reciprocal fromula we know that

Given that:secθ= 5 / 4We need to find the value of cosθAccording to trignometric reciprocal fromula we know that1 / secθ = cosθ

Given that:secθ= 5 / 4We need to find the value of cosθAccording to trignometric reciprocal fromula we know that1 / secθ = cosθSubstituting the given value of secθ in the above equation, we get

Given that:secθ= 5 / 4We need to find the value of cosθAccording to trignometric reciprocal fromula we know that1 / secθ = cosθSubstituting the given value of secθ in the above equation, we get1 / secθ =cosθ

Given that:secθ= 5 / 4We need to find the value of cosθAccording to trignometric reciprocal fromula we know that1 / secθ = cosθSubstituting the given value of secθ in the above equation, we get1 / secθ =cosθ=1 / 5/ 4

Given that:secθ= 5 / 4We need to find the value of cosθAccording to trignometric reciprocal fromula we know that1 / secθ = cosθSubstituting the given value of secθ in the above equation, we get1 / secθ =cosθ=1 / 5/ 4= 4 / 5

Given that:secθ= 5 / 4We need to find the value of cosθAccording to trignometric reciprocal fromula we know that1 / secθ = cosθSubstituting the given value of secθ in the above equation, we get1 / secθ =cosθ=1 / 5/ 4= 4 / 5Hence cosθ = 4 / 5
