A triangle has corners A, B, and C located at #(1 ,3 )#, #(7 ,4 )#, and #(5 , 8 )#, respectively. What are the endpoints and length of the altitude going through corner C?
1 Answer
Endpoints are
Length
Explanation:
We need the equation of the line passing thru A(1, 3) and B(7, 4) by the two-point form
Solve for the length
from the first equation
We need another equation to solve for the endpoints
Use point
simultaneous solution of the two equations to solve for the other endpoint
the other endpoint is
God bless...I hope the explanation is useful.
