the chapter 10 : Angles of Elevation and Deprssions
hello i want a practice the subject math . i hope this my answer is true :)
oke , i the ready to answer a quation ni :)

Solution : 
1. The angle of elevation  from Q to R  ?

            tan O1 = opposite side               
                         adjacentside
            tan O1 = 12
                         10           
            tan O1 = 1.2  
                 O1 = tan-1 1.2
                 O1 = 50.19' or 50'11'

2. The angle of depressions of P from R .

            tan O2 = opposite side
                         adjacentside          
            tan O2 = 12-8
                          10
            tan O2 = 4
                        10
                      = o.4           
                 O2 = 21.8 or 21'48

hehe releks r .sowy sbb aku bg soalan skit kpla . best ape math ni :)
taaadaaa ! itu r jawapan aku . eh elle memey r der , exam na dkt . study r .
