Question

in triangle abc rigth angle at c if ac is equal root 3 bc then prove angle abc is equal 60 degree
​

Answer 1

Answer:

Therefore CD = BD = DA or CD = 1/2 AB = BC. Thus, BC = 80 = CD, i.e., △BCD is a equilateral triangle. Hence, ∠ABC = 60°.

Answer 2

Step-by-step explanation:

Therefore CD = BD = DA or CD = 1/2 AB = BC. Thus, BC = 80 = CD, i.e., △BCD is a equilateral triangle. Hence, ∠ABC = 60°.
