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.
Is that considered two equations?
Answer:
Asanji drove for
hours before Huong caught up
Step-by-step explanation:
Let the time for which Asanji drove alone is "X" hours
Asanji and Huong met after three hours of driving of Huong.
Total time for which Asanji drove
hours
Thus, distance travelled by Asanji in
hours is equal to distance travelled by Huong in
hours

On solving the above equation, we get -

Asanji drove for
hours before Huong caught up
2400 divided by 44% which is 1056.
(sneaky way to put history in math, btw...)
