Question

4. If a pole 10 m, high cast a shadow 10m on the ground, then the sun's elevation
(i) 90°
(ii) 30°
(iii) 45°
(iv) 60​

Answer 1

Answer:

45°

Step-by-step explanation:

given

height = 10 m

base = 10 m

∴ it is a isosceles triangle

the connection of the shadow and pole is 90°

let 'y' be the other angle

∴ y + y + 90 = 180 (sum of interior angles of a triangle is 180°)

2y = 180 - 90

2y = 90

y = 90/2

y = 45°

∴ the elevation of the sun is 45°

Answer 2

Answer:

(iii) 45°

Step-by-step explanation:

given

height = 10 m

base = 10 m

∴ it is a isosceles triangle

the connection of the shadow and pole is 90°

let 'y' be the other angle

∴ y + y + 90 = 180 (sum of interior angles of a triangle is 180°)

2y = 180 - 90

2y = 90

y = 90/2

y = 45°

∴ the elevation of the sun is 45°
