Answer:
15.81 ft .
Step-by-step explanation:
This question is based on " Pythagoras Theorem " . If we imagine the given situation as a right angled triangle , then the base will be " 9ft " , and the perpendicular will be " 13 ft" . And the length of the ladder will be equal to hypontenuse of the triangle.
<u>Using </u><u>Pythagoras</u><u> Theorem</u><u> </u><u>:</u><u>-</u><u> </u>
<u>Hence </u><u>the</u><u> </u><u>length</u><u> of</u><u> the</u><u> </u><u>ladder </u><u>is </u><u>1</u><u>5</u><u>.</u><u>8</u><u>1</u><u> </u><u>ft</u><u>. </u>
My only explanation to that is that you subtract that sum or any other way to get two with that number. Sorry if I didn't help I tried my best...
5x 34 is the correct answer
First, divide 30 by 2, then times that by 20. Or, you could times 30 by 10<span />
