The diagram shows A(-3, 5) and B(8,1). What is the distance between the points?
Enter your answer as a number, without units.
Round your answer to one decimal place, if necessary, like this: 42.5

11.7

Step-by-step explanation:

You can form a right triangle with these points with a base of 11 and height of 4 with the third point as (-3, 1).

Using the Pythagorean Theorem, we get:

The distance from A to B is roughly 11.7 units long.

11.7

Step-by-step explanation:

Use the formula for distance of two points.

d = √( (x2 - x1)²+(y2-y1)²)

d = √( (8 - -3)²+(1 - 5)²)

d = √( (11)²+(-4)²)

d = √( 121+16 )

d = √137 = 11.7047

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
