Answer:
y=4/9
Step-by-step explanation:
Substitute 2y into the x
2(2y)+5y=4
4y+5y=4
9y=4
y=4/9
Answer:
21 feet
Step-by-step explanation:
Given :
Height of the tripod above the ground = 5 ft
Elevation = 8°
Distance of the tree from the tripod = 120 ft
Therefore from the figure, we can find the height of the tress as:


∴ BC ≈ 16
Therefore, CE = BC+BE
= 16 + 5
= 21
Therefore the height of the tree is 21 feet.
