Answer:
443.2m
Step-by-step explanation:
Given in the question that,
distance from building to me = 45m
angle of elevation = 82°
building is 123 m + x m high
If we closely observe then this situation make a right angle triangle and we will use trigonometry identity to solve the question.
Step 1
tan(82) = y / 45
y = 45tan(82)
y = 320.2 m
Step 2
Hence the height of building is y + 123m. So, plug the value of y in this
320.2 + 123 = 443.2
Step-by-step explanation:
- x+x+x=65
- 3x=65
- x=65/3
- x=21.67
If 2/3 of the cards are face-up, then 2/3*12=8 cards are face-up. The remaining 12-8=4 cards are therefore face down.
