Answer 2

Pole and its shadow makes acute angle on the ground​:

Explanation:

• In right angle △ABC,AB represents the vertical pole and BC represents the shadow on the ground. θ represents the angle of sun ray made with the earth.
• In right angled triangle ABC,
• tanθ= AB/BC
• Given that the pole and its shadow have same length, i.e., AB=BC
• ∴tanθ= AB/AB
• ​⇒tanθ=1
• ⇒tanθ=tan(π/ 4)
• ⇒θ= (π/4)
• Hence the angle of sun ray made with the earth is π/4 or 45°.
