Answer:
[45tan(82°)+123] meters
A is correct
Step-by-step explanation:
You are standing 45 meters from the base of the Empire State Building.
You estimate that the angle of elevation to the top of the 86th floor(the observatory) is 82°.
If the total height of the building is another 123 meters above the 86th floor.
OB = 45 m , ∠O= 82°
In Δ OBA, ∠B = 90°



Top of the building, T at 123 m from A
Total height of building = BA + AT

Hence, The height of building from ground is [45tan82°+123] meters
Answer:
6 quarters and 9 nickels
Step-by-step explanation:
6 quarters is equal to $1.50. 6 nickels is equal to $0.30. Those together equal $1.80, then add the three nickels bringing your total to $1.95.
1) vertical line
2) neither
3) horizontal line
4) neither- these two overlap.

5 through 6 equation: a²+b²=c²
5) 5²+.8²=c²
25+.64=c²
√25.64=√c²
√25.64=C or 5.063=C
6) 2²+8²=c²
4+64=c²
√68=√c²
√68=C or 8.246=C
I hope this was of help
