<p> 10cos<sup>2</sup>θ + 7sin<sup>2</sup>θ = 7</p>

<p>⇒ 10(1–sin<sup>2</sup>θ) + 7sin<sup>2</sup>θ = 7</p>

<p>⇒ 10 – 10sin<sup>2</sup>θ + 7sin<sup>2</sup>θ = 7</p>

<p>⇒ 10 – 3sin<sup>2</sup>θ = 7</p>

<p>⇒ 3sin<sup>2</sup>θ = 3</p>

<p>⇒ sin<sup>2</sup>θ = 1</p>

<p>⇒ sinθ = 1</p>

<p>⇒ θ = 90°</p>

<p>⇒ cosθ = cos90° =0</p>

<p>⇒ sinθ + cosθ = 1 + 0 = 1</p>
