Question

what is the angle the ladder makes with the ground if 4.5 M long ladder is placed at 1 m away from the wall

Answer 1

LENGTH of ladder is 4.5m
DISTANCE FROM WALLI IS 1M
THINK IT AS TRIANGLE
THEN
COS$=adj sidee/hyp
i. e. 1/4.5
$=cos-1(1/4.5)
Calculated one is answer

Answer 2

Answer:

The answer is 4.59 meter.

Step-by-step explanation:

Here the height is not known to us.

According to the Pythagoras theorem: In the right-angled triangle the hypotenuse square is equal to the square of the other two sides.

(hypotenuses)²=(Base)²+(height)²

Here hypotenuse is 4.7 meter

base is 1 meter

so,

(4.7)²= (1)²+(h)²

(h)²= 22.09-1

(h)²=21.09

h=√21.09

h= 4.59 meter.

The hypotenuse is 4.59 meter.
