I need help with geomerty!! ?

Question

A has coordinates (3, 8).

B has coordinates (0, -4).

C has coordinates (-5, -6).

88. Find the distance between A and B to the nearest tenth.

22. Find BC to the nearest tenth.

THANK YOU!!

Answer 1

Find the formula in the net... It's hard to express it in here... I'll just answer this... ok?

Distance of A and B....

D= sqrt of { (0-3)^2 + (-4-8)^2 }

..= sqrt of { 9 + 144 }

..= sqrt of { 153 }

..= 12.37 units

Distance of B and C

D= sqrt of { (-5-0)^2 + (-6+4)^2

..= sqrt of { 25 + 4 }

..= sqrt of { 29 }

..= 5.39 units

Answer 2

distance formula: sqrt( (x2-x1)^2 + (y2-y1)^2 )

just make sure you use the corresponding coordinates
