Answer:
20
Step-by-step explanation:
Use the distance equation to find the length of each side:
d = √((x₂ − x₁)² + (y₂ − y₁)²)
where (x₁, y₁) and (x₂, y₂) are the points (the order doesn't matter).
AB:
d = √((-2 − (-2))² + (-2 − 4)²)
d = 6
BC:
d = √((4 − (-2))² + (-2 − (-2))²)
d = 6
AC:
d = √((-2 − 4)² + (4 − (-2))²)
d = 6√2
So the perimeter is:
AB + BC + AC
6 + 6 + 6√2
≈ 20
Answer:
m<M = 113 deg
m<N = 61 deg
Step-by-step explanation:
In an inscribed quadrilateral, opposite angles are supplementary.
m<M + m<K = 180
m<N + m<L = 180
m<M + 67 = 180
m<M = 113
m<N + 119 = 180
m<N = 61
Answer:
The answer would be A, D, and C.
Step-by-step explanation:
y=1, so
1 > 2(1) -2
1> 2-2
1>0 TRUE
NEXT.
y=3
3> 2(-1) -2
3>-2-2
3> -4 TRUE
NEXT
y=-2
4>2(2) -2
4 > 4-2
4>2 TRUE!
I hope this helps!
Answer:
y< -3/2x-2
Step-by-step explanation:
if you look at the graph, you can see the line is dotted, which means it is not equal to. eliminate a and c. the shade is toward the bottom of the y, which then you could eliminate a because b says the y value is greater than, which isn't true. you could also check it by plugging in any value for x!
hope this helped :)
Answer:
x = 6
Step-by-step explanation:
To find the missing side, write a proportion using side lengths from each similar shape. A proportion is an equation that sets equal two ratios.
Find x by cross multiplying numerator and denominator of each fraction.
4(18) = 12x
72 = 12x
6 = x
