Question

Hitung jarak di antara titik P(7, 1) dengan titik Q(7, 8) ​

Answer 1

Answer:

7 units

Step-by-step explanation:

Distance between 2 points

=$\sqrt{(y1 - y2)^{2} + (x1 - x2) {}^{2} }$

Thus, distance PQ

$=\sqrt{(8 - 1)^{2} + (7 - 7)^{2} } \\ = \sqrt{7^{2} } \\ = 7$

Or you could simply take 8-1= 7 since both points have the same x-coordinate. Thus, PQ is a vertical line and the distance between them is due to the difference in their y-coordinate.
