The side lengths of a triangle are 9, 12, and 15. Is this a right triang
O A. Yes, because 9² + 12² > 15².
O B. No, because 9 + 12 ‡ 15.
OC. Yes, because 9² + 12² = 15².
OD. No, because 9² + 12² # 15².
Answer is the A
Answer:
coordinates of B is ( 4,5)
Step-by-step explanation:
If there two points (x1,y1) and (x2,y2) on a plane then coordinates of mid point is given by
m = (x1+x2)/2 , (y1+y2)/2
Given
m = (-1,1)
A= (-6, -3)
we have to point b
let point b be (x,y)
Then m (-1,1) is given by (-6+x)/2 , (-3+y)/2
(-6+x)/2 = -1
-6 + x = 2*-1 = -2
x = -2+6 = 4
also
(-3+y)/2 = 1
=> -3 + y = 2
=> y = 2 + 3 = 5
Thus , coordinates of B is ( 4,5) answer
