Answer:
Vertical Angles
Step-by-step explanation:
each of the pairs of opposite angles made by two intersecting lines.
Answer:
m = 3/2
Step-by-step explanation:
Use the slope formula: (y2 - y1) / (x2 - x1)
It would be 12 because 10 is less than 12 and 12 is less then 13
Answer:
m = -1
Step-by-step explanation:
First write the line in slope intercept form y = mx+b where m is the slope and b is the y intercept
x-y = 6
subtract x from each side
-y = -x+6
Multiply each side by -1
y = x-6
The slope is 1
Perpendicular lines have slopes that multiply to -1
m * 1 = -1
m = -1
The slope of the perpendicular line is -1
Answer: 120 cm.
Step-by-step explanation: Each triangle has 3 sides, and each side is 1 cm. Multiply the number of sides for one triangle by the total number of triangles. 3 x 40=120. The perimeter is 120 cm.
