Answer:
104 units
Step-by-step explanation:
One key thing to note about a reflection is that side lengths and angle measures will always remain the same on the reflected figure. With that in mind, let's note the side lengths in both the original and reflected figures.
Remember, since side lengths are the same, let's fill in the missing values with the values of the side lengths given in each of the figures:
See? Notice how the values are the same! To find the perimeter (
) of a quadrilateral, we have to add each side length:

Subtraction is a mathematical operation that reflects the removal of things from a collection. The ribbon that Millie already had is 7.1 feet.
<h3>What is subtraction?</h3>
Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.
Given Millie needs a total of 7.8 feet of ribbon for a school project. Also, She needs 0.7 more feet of ribbon. Therefore, the ribbon that Millie needs is,
Ribbon Millie had = Total Ribbon - ribbon that is needed
= 7.8 feet - 0.7feet
= 7.1 feet
Hence, the ribbon that Millie already had is 7.1 feet.

Answer:
57.9°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relation between trig functions and sides of a right triangle. Here, you're given the side adjacent to the angle of interest, and the hypotenuse of the triangle. This suggests the CAH relationship is the one of interest:
Cos = Adjacent/Hypotenuse
cos(angle) = (741 ft)/(1393 ft)
angle = arccos(741/1393) ≈ 57.863° . . . . . use the inverse cosine function
angle ≈ 57.9°
The wire makes an angle of approximately 57.9° with the ground.
