Answer: the height of the helicopter is 22.33 yards

Step-by-step explanation:

The diagram illustrating the scenario is shown in the attached photo. A triangle, ABC is formed.

H represents the height of the helicopter.

x + y = 52

x = 52 - y

We would apply trigonometric ratio.

tan # = opposite side/adjacent side.

Tan 48 = H/x

H = xtan48

H = tan48×(52 - y)

H = 1.1106(52-y)

Also,

Tan 35 = H/y

H = ytan35

H = 0.7002×y

H = 0.7002y

Since H = H, therefore

1.1106(52-y) = 0.7002y

57.7512 - 1.1106y = 0.7002y

0.7002y + 1.1106y = 57.7512

1.8108y = 57.7512

y = 57.7512/1.8108

y = 31.89

Recall,

H = 0.7002y

H = 0.7002 × 31.89 = 22.33 yards

The sum of the three angles is 180. One is given and the other we can figure out because it forms a straight line (180) with the angle to the left outside. The outside angle is 117, so 180-117 is 63.
So then add up the 3 angles in the triangle
63+35+y=180
y= 82

Step-by-step explanation:

Using the properties of logarithms, the left side of the equation becomes

$\log{3x^3} - \log{x^2} = \log{3x}$
