Best ResponseYou've already chosen the best response.3imagine a line from the top point to the middle of the base. You now have two right angled triangles. Use pythagoras' theorem on one to find the height (the line you've drawn in) a^2+b^2=c^2 a=96/2=48 b=the height c=102 48^2+b^2=102^2 2304+b^2=10404 b^2=104042304=8100 b=sqrt(8100) b=90

Best ResponseYou've already chosen the best response.3b=90, so b is answer D! Do you understand it?

Best ResponseYou've already chosen the best response.3use pythagoras' theorem again. in this case: a=sqrt(40) b=3 c=z on the diagram so: sqrt(40)^2+3^2=c^2 40+9=c^2 49=c^2 c=sqrt(49) c=7 :)

Best ResponseYou've already chosen the best response.3are you actually understanding this or just taking the answers? if you're learning you should be able to work this out now. remember, for right angled triangles, just use pythagoras' theorem!

Best ResponseYou've already chosen the best response.3so you are doing the attached one? do you know pythagoras' theorem?

Best ResponseYou've already chosen the best response.3correct :) in this case you need to find a, so rearrange the equation so that a is by itself

Best ResponseYou've already chosen the best response.1but the square root how do i figure that

Zara

Best ResponseYou've already chosen the best response.3when you rearrange, the equation is: a^2=c^2b^2 i think you mean sqrt(53)=z? In pythagoras' theorem, the z is the equivalent of c because it is the hypotenuse, so you subsitute this into the equation: a^2=sqrt(53)^2b^2 when you square a square root, you're basically just getting rid of the square root, so sqrt(53)^2=53 does that help?
