Answer: D) 8
If there's a way to solve this fast I totally forgot it but this was easy enough to solve with substitution. I'd ask your teacher about this one but the answer is definitely D) 8.
Idk buddy you may need to ask your teacher about that or pay attention in class next time
Answer:
19.1 ft
Step-by-step explanation:
-This a Pythagorean theorem problem given by the function:
![b^2+h^2=H^2](https://tex.z-dn.net/?f=b%5E2%2Bh%5E2%3DH%5E2)
Where
H is the Hypotenuse length
h is the perpendicular height
b is the base length.
#Given that H=20 ft and base length,b =6 ft, the perpendicular height is calculated as:
![h^2+b^2=H^2\\\\h^2=H^2-b^2\\\\h^2=20^2-6^2=364\\\\h=\sqrt{364}\\\\=19.0788\approx 19.08\ ft](https://tex.z-dn.net/?f=h%5E2%2Bb%5E2%3DH%5E2%5C%5C%5C%5Ch%5E2%3DH%5E2-b%5E2%5C%5C%5C%5Ch%5E2%3D20%5E2-6%5E2%3D364%5C%5C%5C%5Ch%3D%5Csqrt%7B364%7D%5C%5C%5C%5C%3D19.0788%5Capprox%2019.08%5C%20ft)
![\approx 19.1 \ ft](https://tex.z-dn.net/?f=%5Capprox%2019.1%20%5C%20ft)
Hence, the ladder reaches the wall at a height of 19.1 ft
Answer:
B is the right answer
Step-by-step explanation:
Subtract 14 from each side to get the value of m
21 - 14 = 7 = m
m = 7
