Question

if the height of tower is 10m and a person 10m away from foot of tower observed top of tower what is angle of elevation??​

Answer 1

Answer:

45 degrees

Step-by-step explanation:

Draw a triangle 10 cm in height and 10 cm base, it is a right angle triangle.

It is also a isosceles triangle

Therefore the other 2 angles are equal because angles oppsite to equal sides are equal.[not the right angle]

There fore by angle sum property,

x + x + 90 = 180

2x = 180 - 90

x = 90/2

x = 45 degrees

Happy to help

And pls mark as brainliest

Answer 2

Answer:

Let h of tower be 'AB' and dist be 'BC'

/C is angle of elevation

tan /C = AB/ BC

           = 10/10

           = 1

tan /C = tan 45

/C = 45 degrees
