Answer:

25) 3 = 5 + secΘ where we have 2 possible values of Θ (2π/3 or 4π/3)

<em>3 = 5 + sec (2π/3)</em>

<em>3 = 5 + sec (120 degrees)</em>

<em>3 = 5 + (-2)</em>

<em>3 = 3</em>

theta =  4π/3

<em>3 = 5 + sec (240 degrees)</em>

<em>3 = 5 + (-2)</em>

<em>3 = 3</em>

Therefore, the equation is true for both 2π/3 and 4π/3

27) -2 SinΘ = -1                {π/6 , 5π/6}

<em>-2 * sin(π/6) = -1 </em>

<em>sin(π/6) = 1/2</em>

1/2 = 1/2

LHS = RHS

theta  = 5π/6

<em>-2 sin(5π/6) = -1 </em>

<em>sin(5π/6) = 1/2 </em>

1/2 = 1/2

LHS = RHS
