Question 821775: the chord 'AB' of a circle with centre 'O' and radius 10cm ,is of length 16cm .'OP' has been drawn perpendicular to the chord AB.OPproduced meets the circle at Q. find the length PQ.?
2)SOLVE THE EQUATION (2* lg x +lg 3 = lg 48)
03) a hollow prism wuth a cross setion in the shape of an eqilateral traingke has been made by folding a rectangular piece of paper.the surface aea of the prism is 450cm squared.and it's length is 30 cm .find the length of a side of it's cross section?

2)SOLVE THE EQUATION (2* lg x +lg 3 = lg 48)
log(x^2) + log(3) = log(48)
---
log(3x^2) = log(48)
3x^2 = 48
x^2 = 16
x = 4

-----
Area of each side of the prism = 150 cm^2
LW = 150
30W = 150
Width = 5 cm
