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°
