<u>Given </u><u>:</u><u>-</u><u> </u>
- An extension ladder with 3 five-foot extensions is leaned against a wall with the base of the ladder 5 feet from the base of the wall.
<u>To </u><u>find</u><u> </u><u>:</u><u>-</u>
- How high on the wall does the top of the ladder sit?
<u>Solution</u><u> </u><u>:</u><u>-</u><u> </u>
Using Pythagoras Theorem ,
- 5² = 3² + h²
- 25 = 9 + h ²
- h² = 25 - 9
- h ²= 16
- h =√16
- h = ±4
- h = 4
Answer:
17° 43"
Step-by-step explanation:
Answer choice a because 4=1+3 and 2=-1+3 and 3=0+3 all those are true therefore the equation y=x+3 is the correct answer.
Answer 0.40
Step by Step
3/20=0.15
25.% (move the decimal back two places) 0.25
0.15+0.25=0.40
3/11 x 5/11
15/121 would be the probability. I am not sure if it can simplify any more! :)
