اريد حل لسؤلين واثبات لو سمحتم
find the root of axx+by+c=0-
2-اثبات قانون جيب التمام
3-
A church spire , 100ft high,bears N.60 degree w from afixed point & its top has an angle of elevation of 30 degree . what are the coordinates of its top with respect to axes as follows
x-axis due to north
y-axis due to vertically up wards
y-axis due to east
through the fixed point as origin
طلب كمان لو في كتاب هندسة فراغية في شرح بسهولة ومبسط خالص للطلبة
بس من البداية الهندسة خالص
