Answer 1

Answer:

=$\sin {}^{2} 30 \cos {}^{2} 45 + \tan {}^{2} 30 + \frac{1}{2} \sin {}^{2} 90$

=$\frac{ {1} }{2}^{2} \times \frac{1}{ \sqrt{2} } {}^{2} + 4 \times \frac{1}{3} {}^{2} + 1 \frac{1}{2} - 0 + \frac{1}{24}$

=$\frac{1}{4} \times \frac{1}{2} + \frac{4}{3} + \frac{1}{2} + \frac{1}{24} \\ = \frac{48}{24} = 2$
