Question

Points F (0,0), G (9,0), and H (9,12) are the vertices of a triangle.

What is the distance from point F to point H?

Answer 1

15 units

Explanation:

`d_(FH)=√((x_H-x_F)^2+(y_H-y_F)^2)\\\\F(0,0)\quad \implies\quad x_F=0\,,\ \ y_F=0\\\\H(9,12)\quad \implies\quad x_H=9\,,\ \ y_H=12\\\\d_(FH)=√((9-0)^2+(12-0)^2)=√(81+144)=√(225)=15`
