Answer:
9 m
Step-by-step explanation:
Suppose AB is the ladder. AC is the height of the window above the ground and BC is the distance of the foot of ladder from the wall.
The triangle ABC is right angled at C.
∴ AB² = AC² + BC²
=> 15² = 12² + x²
=> 225 - 144= x²
=> 81 = x²
=> 9 = x
- Hence, distance of the foot of the ladder from the wall is 9 m.
Answer:
(2.6, -2.7)
Step-by-step Explanation:
Let X represent the point which is 7/10 of the way from A to B.
AX to XB = 7:10 = AX/XB = 7/10.
Formula for internal division to find the coordinates is:
Where,
Substitute the values above into the stated formula to find x and y coordinates as follows:
The coordinates of the point 7/10 of the way from A to B are (2.6, -2.7)
