The perimeter is the total length of all sides of the shape.
It is 1 meter + 1 meter + 2 meter + 2 meter = 6 meters
1 meter = 100 centimeter
6(100) = 600 centimeter
Hope this helps! :)
Answer:
x=18
Step-by-step explanation:
So (3x+20)° and (5x-16)° are angles that are vertically opposite to each other; which means that they are equal to one another. Which means we can say:
(3x+20)=(5x-16)
20+16=5x-3x
36=2x
x=18
*and the two angles are 74°
Answer:
#2. 1 = 50° 3 = 50° 4 = 130°. 2. ∠3=137°
Answer:
no solutions
Step-by-step explanation:
3x - 6y= -12
x - 2y= -8
Solve the second equation for x
x-2y=-8
Add 2y to each side
x-2y+2y = -8+2y
x = -8+2y
Substitute this into the first equation every place to see x
3x-6y=-12
3(-8+2y) -6y=-12
Distribute the 3
-24 +6y -6y =-12
-24 = -12
Since this is never true there are no solutions.
