Hello:) anyone able to help with 7? Thank you!

Angle of depression from C to T measures approximately

Step-by-step explanation:

To start, we use triangle DTA to find the length of the side AT, making use of the tangent function:

Now we need to find the size of the rectangular land diagonal:

With this information, we can now find the measure of angle "C" (depression angle from C to T), using the triangle ACT:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
