<u>Answer:</u>
Oak tree is 33 ft tall.
<u>Step-by-step explanation:</u>
We know that Irene places a mirror on the ground and walks backwards such that the mirror is in between her and the oak tree (as shown in the attached picture).
Given the distance of Irene's eyes from ground, distance between oak tree and mirror and distance between mirror and Irene, we are to find the height of the tree.
For this, we will use the ratio method:

T = 33 ft
Answer:
D
Step-by-step explanation:
Simplify and rearrange to solve.
2/3 (cx + 1/2) - 1/4 = 5/2
2/3 (cx + 1/2) = 5/2 + 1/4
2/3 (cx + 1/2) = 11/4
cx + 1/2 = 11/4 divided by 2/3
cx + 1/2 = 33/8
cx = 33/8 - 1/2 = 29/8
x= 29 / 8 divided by x = 29/8c.
Hope this helps.
Answer:

Step-by-step explanation:
i would say C. because since its 4 times the radius then you factor in thats only half of the circle then you factor in the other side which makes it 8 hope this is true
