You wre flying a drone at a height of twelve yards. It has traveled a horizontal of twenty eight. What is the angle of depression from the drones current location down to its starting point

23.19°

Step-by-step explanation:

Given that,

The height of a drone = 12 yards

It has traveled a horizontal of 28 yards

We need to find the angle of depression from the drones current location down to its starting point. It can be calculated as :

So, the angle of depression is equal to 23.19°.

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
