How can you move just one number to a different triangle to make the sum of the numbers in each
triangle equal? (Hint: There do not have to be
exactly 3 numbers in each triangle.)

Remove 9 from triangle B to A

Step-by-step explanation:

Given

Three Triangles

A: 1,2,3

B: 7,8,9

C: 4,5,6

Required

Make their sum equal

First, we need to calculate the sum in each triangles;

Remove 9 from triangle B to A

At this point, we have:

Hence, the solution is to remove 9 from B to A

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
