Graph the image of rectangle STUV after a reflection across the line x = -2
1 answer:
Answer: see image
<u>Step-by-step explanation:</u>
Draw line x = -2. Count how many units away each point is from line x = -2 and create the new points the same number of units away from line x = -2 but in the opposite direction.
S is 5 units to the right of x = -2. The new point S' is 5 units to the left of x = -2.
T is 6 units to the right of x = -2. The new point T' is 6 units to the left of x = -2.
U is 6 units to the right of x = -2. The new point U' is 6 units to the left of x = -2.
V is 5 units to the right of x = -2. The new point V' is 5 units to the left of x = -2.

Answer:
149.43 feet tall
Step-by-step explanation:
From the base of a large tree, a bird watcher is standing 50 feet away.
There is 71.5° of elevation from the bird watcher to a bird on the top of the tree.
If we ignore the height of the observer and consider the height of the tree as h feet, then using trigonometry we can write that
tan 71.5° = =
Hence, h = 50 tan 71.5° =149.43 feet.
Therefore, the tree is 149.43 feet tall. (Answer)
