Question

i am stuck on question 3, this is just a review and my teacher said i could have some help if i need it but it needs to be turned in by tomorrow. so if you could help that would be very appreciated

Answer 1

Given,

The coordinates of point H is (-9, 5).

The coordinates of point A is (-1, 8).

Required

The value of HA.

The distance between the point A and H is,

$\begin{gathered} HA=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\ =\sqrt{(-9+1)^2+(5-8)^2} \\ =\sqrt{(-8)^2+(-3)^2} \\ =\sqrt{64+9} \\ =\sqrt{73} \\ =8.5 \end{gathered}$

Hence, the measure of HA is 8.5.
