Answer:
D. 1/15
Step-by-step explanation:
Actual tree = 10 ft = 12 × 10 = 120 in.
Model tree = 8 in.
Scale factor = model tree/actual tree
Scale factor = 8/120
Scale factor = 1/15
See the attached figure.
m ∠KAJ = 170° & m ∠LAM = 80°
We should know that :
m ∠KAJ + m ∠LAM + m ∠KAL + m ∠MAJ = 360°
∴ m ∠KAL + m ∠MAJ = 360° - (m ∠KAJ + m ∠LAM)
∴ m ∠KAL + m ∠MAJ = 360° - (170°+80°) = 360° - 250° = 110°
But : m ∠KAL = m ∠MAJ ⇒⇒⇒ <u>Opposite angles.</u>
∴ m ∠MAJ + m ∠MAJ = 110°
∴ 2 * m ∠MAJ = 110°
∴ m ∠MAJ = 110° ÷ 2 = 55°
<u>So, the answer is : m ∠MAJ = 55°</u>
Using an ordered pair is a way of graphing a linear equation on a coordinate plane.

Answer:
29,035.43 meters
Step-by-step explanation:
What we know:
- The elevation of the shore of the Dead Sea is -1,344.99 meters.
- The summit of Mt. Everest is 30,380.42 meters above the Dead Sea.
So, we just add the two values.
30,380.42 + (-1,344.99)
We can rewrite this as 30,380.42 - 1,344.99 since adding a negative is the same as subtracting that number.
And we get 29,035.43 meters as the elevation or height of Mt. Everest.
