Answer:
7
Step-by-step explanation:
if the stick is 7.5 divide that by 3 and you get 2.5 so divide 17.5 by 2.5 and you get 7 .
<2 + <5 = 180 this is a straight line
<2 + 150= 180
subtract 150 from each side
<2 = 30
<2 + <3 + <4 = 180 a triangle is 180 degrees
30 + <3 + 70 = 180
100 + <3 = 180
<3 = 80
Answer: The distance between a and c is 8 units
Step-by-step explanation:
You can count the number of units they are apart, but if there isn’t a grid, then do this:
If x or y values in the ordered pairs are different, subtract them from each other and find the absolute value of the difference. (It’s my own rule, so there is a better method. My explanation apples only to ordered pairs that share a x or y value, like A and C)
2-(-6) = 8, and the absolute value of 8 is 8
Or
(-6)-2 = (-8), and the absolute value of -8 is 8 (You’ll get the same answer)
D=(S+8)/C
S=DC-8
add 8 to both sides
S+8=DC
divide c from both sides
(S+8)/C=D
