Question

The length, breadth and height of a room
are 10 m, 10 V2 m and 10 m respectively.
The angle of elevation of a top corner of
room from any point on a diagonal of the
base of the room is
1) 45° 2) 60° 3) 30°4) None


fastly tell me answer​

Answer 1

Answer:

since the perpendicular and base is equals to 10 m and the hypotneuse is equal to 10 root 2 and also the sin and cos theta for 45 degress is equals to root 2  so the the angle of inclination will be equal to 45 degreees

Step-by-step explanation:

sin theta=1/root2

and 10 /10root 2 is equals to root 2

Answer 2

Answer:

since the perpendicular and base is equals to 10 m and the hypotneuse is equal to 10 root 2 and also the sin and cos theta for 45 degress is equals to root 2 so the the angle of inclination will be equal to 45 degreees

Step-by-step explanation:

sin theta=1/root2

and 10/10root 2 is equals to root 2
