Question

A ladder is placed aganist a wall at a height of 8 ft .If the base of the ladder is 15 feet from the base of the wall .Find the length of the ladder​

Answer 1

Answer:

17

Step-by-step explanation:

ladder=h

wall height=p=8

base=b=15

according to Pythagoras theorem

H^2=P^2+B^2

H^2=8^2+15^2

H^2=64+225

H^2=289

H=ROOT 289

H=17

Answer 2

Answer:

Step-by-step explanation:

Length ladder

= $\sqrt{a^2+b^2}$

= $\sqrt{8^{2} +15^{2}$

= $\sqrt{64+225}$

= $\sqrt{289}$

= 17
