Answer:
2.meters
Step-by-step explanation:
Lenght of ladder = 4 m
θ = 30°
To obtain h;
Using Pythagoras rule :
Sinθ = opposite / hypotenus
Hypotenus = 4 ; opposite = h
Sin 30 = h / 4
0.5 = h / 4
h = 0.5 * 4
h = 2 m
Hence, distance between th efoot of ladder and the base of the wall is 2 m
If 15 is 1/4 of an hour then multiply 12 with 4. It’s 48, they can hang 48 sheets in an hour.
Answer:
AB= 8/Cosine 60 degrees
Step-by-step explanation:
Cosine=Adjacent/Hypotenuse
Cosine=8/AB
AB=8/Cosine 60 degrees
The square root of thirty lies between the numbers 5 and 6.
