D. 15m wide
D)
15x17=255
15=12+3 17=14+3
Answer: 19 ft
Step-by-step explanation:
Hi, we have to apply the Pythagorean Theorem, since the tree and the ladder form a right triangle. (see attachment)
Hypotenuse squared = side squared + side squared.
Hypotenuse of a right triangle is the longest side.
Replacing with the values given:
x^2 = 18^2 + 6 ^2
Where x is the length of the ladder.( because is the longest side)
Solving for x:
√(18^2 + 6 ^2)= x
19 ft
