Yeah a good way to do reflections is to remember a is the x coordinate b is the y coordinate
X- axis (a, -b)
Y - axis (-a, b)
Y = x (b, a)
Y = - x (- b, -a)
Answer:
The tree is about 8 feet.
Step-by-step explanation:
7 2/3 = 7.6 as a fraction.
30 1/5 = 30.5 as a fraction.
Know, we must divide 30.5 by 7.6.
30.5 ÷ 7.6 = 4 when rounded to the nearest whole number.
Since we know that the stake is 2 feet, we must multiply this by 4, since the other shadow is 4 times the amount of the stake.
2 x 4 = 8
This means the tree is about 8 feet.
