Answer:
Supplementary angles are those angles that sum up to 180 degrees. For example, angle 130° and angle 50° are supplementary angles because sum of 130° and 50° is equal to 180°.
Step-by-step explanation:
Answer:
32°
Step-by-step explanation:

Step-by-step explanation:
Answer:
3.6 and 1.2
Or
-3.6 and -1.2
Step-by-step explanation:
Let x and y be the two numbers
xy = 4.32
x/y = 3
x = 3y
3y² = 4.32
y² = 1.44
y = +/- 1.2
x = +/- 3.6
Answer:
Step-by-step explanation:
you need to find the distance between points L, M, N to know the length of sides LM, MN, NL
use the distance formula
d= √(x2-x1)² +(y2-y1)², where the points are (x1, y1) and (x2, y2)
LM = √(4-1)² + (-3- -3)² = √3² + 0² = 3
MN = √(1-1)² + (-3-0)² = √0² + 9 = 3
NL = √(4-1)² + (-3-0)² = √3² + 9 = √18 = 3√2
The perimeter is LM+MN+NL = 3+3+3√2 = 6+3√2 ≈ 10.243
