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
Answer:
A. 15.7 ft
Step-by-step explanation:
circumference = 2πr
radius= half the diameter 5/2=2.5
2(3.14)(2.5)=15.7 ft
Answer:
p - a - c = b
Step-by-step explanation:
p = a + b + c
subtract a and b from both sides to isolate c
p - a - c = a - a + b
+ c - c
The answer is B. Infinitely many solutions. <span />
For this case we must find the value of the variable "x" of the following equation:
We multiply by 3 on both sides of the equation:
We divide between 2 on both sides of the equation:
We subtract 7 on both sides of the equation:
Answer:
Option B
