Lego has unveiled its first bricks made from recycled plastic bottles and ( 11 ) that it hopes to include the pieces in sets within two years. The prototype 4x2 bricks have been made from PET plastic from ( 12 ) bottles with additives to give them the strength of standard Lego parts, and are the result of three years of ( 13 ) with 250 variations of materials. It has already ( 14 ) plans to remove single-use plastic from boxes, and since 2018 has been ( 15 ) parts from bio-polyethylene (bio-PE), made from sustainably sourced sugarcane.

ベクトルのなす角の問題です。 なす角の範囲を0°≦γ≦180°とした後、γの値が60°と120°になる所までは分かったのですが、なぜ最終的な答えが120°になるのでしょうか。なす角とは普通鋭角だと思って60°と答えてしまいました。

203 大きさが2で, x軸の正の向きとなす角が45℃, y 軸の正の向き となす角が60° であるような空間のベクトルを成分表示せよ。 ま た, そのベクトルがx軸の正の向きとなす角は何度か。
