Now i don't know if you'll get this right because it'ts tough! But what is 1+1.

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles

In triangle opq right angled at p op=7cm,oq-pq=1 determine the values of sinq and cosq

Apinhole camera is made out of a light-tight box with a piece of film attached to one side and pinhole on the opposite side. the optimum diameter d(in millimeters) of the pinhole can be modeled by d=1.9[ (5.5 x 10^-4) l) ] ^1/2, where l is the length of the camera box (in millimeters). what is the optimum diameter for a pinhole camera if the camera box has a length of 10 centimeters
