Answer:
7.8
Step-by-step explanation:
distance formula : 
where the x and y values are derived from the given points
here the given points are (11,3) and (6,9)
<u>assigning variables</u>
(x1,y1) = (11,3) so x1 = 11 and y1 = 3
(x2,y2) = (6,9) so x2 = 6 and y2 = 9
<u>plugging in values into formula</u>
recall formula
==> plug in x1 = 11 , y1 = 3 , x2 = 6 and y2 = 9
==> subtract values in parenthesis
==> evaluate exponents
==> add 25 and 36
( approximately )
Answer:
18
Step-by-step explanation:
A : B
1 : 4½
4 : X
1/4.5 = 4/X
X = 4×4.5 = 18
I think its D)
Because when you look at the x-axis 3 and go up to the y-axis its 4
Answer:
Step-by-step explanation:
55 +80 + ∠C = 180 {Angle sum property}
135 + ∠C = 180
∠C = 180 - 135
∠C = 45
The side opposite to the biggest angle is the longest side
Biggest angle is ∠B. So the longest side is AC
Smallest angle is ∠C. So, the shortest side is BA
The answer would be 248 inches
