Question

let ABC be an equilateral triangle in which co-ordinate of B and C are (5,0) and (-5,0) respectively. find the co-ordinates of A

Answer 1

Answer:

Step-by-step explanation:

length a = 5 - (-5) =10

height of triangle =√( 10^2 - 5^2) =√75 =5√3

so co ordinate of A = (0,5√3)

Answer 2

Answer:

length = 5-(-5)=10

Height of triangle = root 10²-5²

= root 75

=5 root 3

coordinates of A=(0,5root 3)

Step-by-step explanation:

ABC equilateral triangle coordinates of Band C are (5,0), and (-5,0) . coordinates point of the point A. equilateral triangle 3 side equal 3 side equal digit 10

solution:

root 10² -5²

root 75

0,5 root 3
