Question

A painter leans a 20 ft ladder against a building. The base of the ladder is 8 ft from the building. To the nearest foot, how high on the building does the ladder reach

Answer 1

Answer:

Step-by-step explanation:

This is asking what is A

Formula A squared + B squared = C squared

A=x

B=8

C=20

X^2+ 8^2=20^2

8 squared is 64

20 squared is 400

400-64 is 336

X*X=336 find the square root of 336 =18.3

CHECK

18.3*18.3+ 8*8=398.89 which is super close to 400
