sin16°是：0.2756373558169991856499715746113
9÷0.2756373558169991856499715746113
=32.651597506889700877809077266826
答：斜边长是32.651597506889700877809077266826.
2、如邻边长是9米：
cos16°是：0.96126169593831886191649704855706
9÷0.96126169593831886191649704855706
=9.362694922754418874050430602189
答：斜边长是9.362694922754418874050430602189
