Answer:

You must first divide 3 from both sides.

Step-by-step explanation:

Whenever you solve an equation such as this you are always trying to isolate the variable that is given. In this case we are arriving at the value of d alone.

3d = -81

d = -27

Hope this helps!

astraxan [27]
11 = C/2-1 + C/2 + C
12 = C/2 + C/2 + C
12 = 4C/2
12 = 2C
C = 12/2
C = 6
Hence, tree A is 2m (3-1), tree B is 3m (6/2) and tree C is 6m

Hi there!

We can use right-triangle trigonometry to solve.

We are given the HYPOTENUSE and ADJACENT sides, so we must use cosine in this instance.

cosθ = Adjacent/Hypotenuse

We can plug in what is given:

cos(28) = A/17

Solve for 'A':

17cos(28) = <u>15.01 ft</u>
