the great pyramid of Cheops is a square based pyramid. the base has sides of 230m and the height is 147m. using the same material. what would the height be if you gave the base sides of 220m?

Step-by-step explanation:

A ratio problem

   230 sides is to 147 height as 220 sides is to an unknown height X

   230/147  =  220 / X    solve for x    ( since 220 < 230  X should be < 147)

   X = (220)(147) / 230

   X = height =  140.6 m      is less than 147

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
