miss i didn't understand how did you get the answer 5.9 is Q 7
In Q7, OP is the hyp. For the given angle 25, 2.5 is the opposite and OP is the hypSo , sin25=2.5/OPFrom this, OP = 2.5/sin25 = 5.9

Miss in question 6a the answers i got when i was practicing are x=2.2 and y=2.4 here are the steps:AB square+BC square=AC square 2 square +x square=3 square =9-4=x square x square=9+4=5so x=square root of 5 =2.2and for y=AB square +BC square =AC square=2.2 square +1 Square=1 =y square =5+1 =6 so the square root of 6=2.4
yes u r correct....

ReplyDeletehere are the steps:
AB square+BC square=AC square
2 square +x square=3 square =9-4=x square x square=9+4=5
so x=square root of 5 =2.2
and for y
=AB square +BC square =AC square
=2.2 square +1 Square=1 =y square =5+1 =6 so the square root of 6=2.4
yes u r correct....
