Answer:
12 feet ladder
Step-by-step explanation:
Height of 12 ft ladder :
Using Pythagoras :
Tan θ = Adjacent / hypotenus
Tan 57 = h / 12
1.5398649 * 12 = 18.48 feets
For 16 feet ladder :
Tan θ = Adjacent / hypotenus
Tan 30 = h / 16
0.5773502 * 16 = 9.24 feets
18.48 > 9.24
Hence, he'll climb the 12 feets ladder to the higher height
The ratio is 2 : 9
Step-by-step explanation:
Given:
The number of sports store = 4
The number of clothing store = 9
The number of jewellery stores = 5
To Find :
The ratio of number of sports stores to the total number of stores
Solution:
The ratio of number of sports stores to the total number of stores
=
The total number of stores = number of sports store + number of clothing store + number of jewellery store
The total number of stores = 4 + 9 + 5
The total number of stores = 18
Now the ratio is
= or 4 : 8
The ratio after reduction is
= or 2 : 9 or 2 to 9
