Distance between points

choose all that correctly give the distance in the coordinate plane between two points.

(−5, 8), (5, 8)
d = 10

(3, 8), (3, −6)
d = 12

(−2, −9), (−2, 4)
d = 13

(8, −7), (1, −7)
d = 9

(−12, −4), (−6, −4)
d = 6

(−5, 8), (5, 8)

d = 10

(−2, −9), (−2, 4)

d = 13

(−12, −4), (−6, −4)

d = 6

Step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
