With a quick question? ? what is value of x? enter your answer in the box. x =

x =10

Step-by-step explanation:

We can use proportions to solve this problem.  Take the small triangles side over the large triangle side

8          x+4

=

12          2x+1

Solve using cross products

8(2x+1) = 12(x+4)

Distribute

16x+8 = 12x+48

Subtract 12 x

16x-12x+8 = 12x-12x+48

4x+8 = 48

Subtract 8 from each side

4x+8-8 = 48-8

4x= 40

Divide by 4

4x/4 = 40/x

x =10

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
