Answer:
AB = 10
BC ≈ 11.40
Step-by-step explanation:
The distance formula is useful for finding distances between points.
d = √((x2 -x1)² +(y2 -y1)²)
AB = √((18 -10)² +(4 -10)²) = √(8² +(-6)²) = √100
AB = 10
__
BC = √((25 -18)² +(-5-4)²) = √(7² +(-9)²) = √130
BC ≈ 11.40
_____
A sketch tool can be useful for finding or checking the answer.
Answer:
Step-by-step explanation:
(2x+4)° + 42° = 180°
x = 67°
Answer: x-y=2
Step-by-step explanation:
y+5=x+3; move variable (x) to the left-hand side and change the sign.
y-x+5=3; move the constant to the right-hand side & change the sign
y+x=3-5; reorder the terms
-x+y=3-5; calculate
-x+y=-2; change the signs on both sides
x-y=2 is your answer! hope this helps!
