Question

find the value of cos60 geometrically

​

Answer 1

Step-by-step explanation:

Step-by-step explanation:Let ABC be an equilateral triangle whose all the three sides are equal to K. Since, ABC is an equilateral triangle, thus all the angles of the given triangle will be equal to 60°.

Step-by-step explanation:Let ABC be an equilateral triangle whose all the three sides are equal to K. Since, ABC is an equilateral triangle, thus all the angles of the given triangle will be equal to 60°.Now, draw AD ⊥BC, thus by geometry, AD bisects ∠BAC and also bisects the side BC.
