Answer:
Step-by-step explanation:
altitude = sqrt(6*8) = 4*sqrt(3)
Use the Pythagorean Theorem to derive x
altitude^2 + 18^2 = x^2
48 + 18^2 = x^2
x^2 = 342
x = 3*sqrt(38)
x = 18.49

Answer:
145 yd²
Step-by-step explanation:
There will be dour triangular faces. For a triangle, area is given as
A=½bh where b is base and h is height. The base will be 5 yards and h is 12 yards hence for one triangular face, area will be ½*5*12=30 yd²
Since they are four similar triangles, area of triangular faces will be 30*4=120 yd²
The surface area of a square base is given by
A=a*a=a² where a is the dimension of one side. Given that the meaurement is 5 yards then A=5²=25 yd²
Total area will be the sum of triangular and square faces hence 120+25=145 yd²
There would be 868 steps. since there is 245 MORE steps in castle be than in castle a, you would have to add 623 to 245
