Question 752035: 10. Point A is the origin. Find the coordinates of the two points that are 5 units distant from A, and have x-coordinates of +3. (Hint: Make a sketch. The two points fall on the line x=3, and therefore have coordinates (3,y) where y is unknown. Use the distance formula, suitably rearranged.)

Draw a circl of radius 5, and you'll see this question is a triangle with a base of 3, therefore the height is 4. (3,4) and (3,-4) are two pints on the circle that hav x = 3
