Answer:
≈ 27 ft
Step-by-step explanation:
using the tangent ratio in the right triangle formed by the building and the ground.
tan15° = 
= 
( multiply both sides by 100 )
100 × tan15° = ? , then
? ≈ 27 ft ( to the nearest whole number )

Answer:
for what?
Step-by-step explanation:
Answer:
For 2 months
Step-by-step explanation:
Let after x months the cost of each health club is same,
Now, In club A,
Membership fees = $ 19,
Monthly fees = $ 21,
So, the total fees for x months = membership fees + total monthly fees for x months
= 19 + 21x
In Club B,
Membership fees = $ 23,
Monthly fees = $ 20,
So, the total fees for x months = membership fees + total monthly fees for x months
= 23 + 20x
Thus, we can write,
19 + 21x = 23 + 20x
21x - 20x = 23 - 21
x = 2
Hence, for 2 months the total cost of each health club would be same.
Answer:
3 7/8
Step-by-step explanation:
6 1/4 = 25/4 and 2 5/8 = 19/8
