Web$$\overline{x^2(t)}=\frac{1}{2T}\int_{-T}^T x(t) ^2dt$$ Note that \$\cos^2 x=\frac12 (1+\cos(2x))\$ and \$\sin^2 x=\frac12 (1-\cos(2x))\$. So after integrating over one period, the terms with double frequency and also the cross-term cancel out. So you finally get for the power $$\overline{x^2(t)}=10^2\cdot \frac12 + 5^2\cdot\frac12=62.5$$
