Nicolas places his 30 ft ladder against his house he is painting. if the foot of the ladder is 8 ft from the base of the house, how high above the ground is the top of the ladder touching the house. nearest tenth. pythagorean’s theorem

28.9'

Step-by-step explanation:

Using the Pythagorean Theorem:

Let a = 8' base

Let b = x

Let c = 30' ladder

a^2 X b^2 = c^2

(8)^2 X (x)^2 = (30)^2

64 X (x)^2 = 900  (Subtract 64 from both sides of the equation)

x^2 = 836

x = 28.9'

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
