Question
If sec θ = `25/7`, complete the following activity to find the value of tan θ.
Activity:
We have, 1 + tan2θ = sec2θ
∴ 1 + tan2θ = `square`
∴ tan2θ = `625/49 - square`
∴ tan2θ = `(625 - 49)/(49)`
∴ tan2θ = `square/49`
∴ tan2θ = `square`

Solution
We have, 1 + tan2θ = sec2θ
∴ 1 + tan2θ = \[\boxed{\left(\frac{25}7\right)^2}\]
∴ tan2θ = `625/49 -` \[\boxed{1}\]
∴ tan2θ = `(625 - 49)/49`
∴ tan2θ = \[\frac{\boxed{576}}{49}\]
∴ tan2θ = \[\boxed{\frac{24}7}\]
