Answer:
x=48
Step-by-step explanation:
10x-20+6x+8=180 set the equations together and to equal 180 since a line is 180 degrees
Get the variables together
10x-20+6x+8=180
-6x -6x
4x-20+8=180
add together -20 and 8
4x-12=180
add -12 on each side
4x-12=180
+12 +12
4x=192
divide all by 4
x=48

Answer:
Perimeter= 40 units
Step-by-step explanation:
Ok
We are asked to look for the perimeter.
We have some clue given.
All at right angle and some sides are given it's full length.
We have the bae to be 11 unit
The height to be 7 unit.
What this mean is that taking either the base or the height should sum up to either 11 or 7 respectively.
Let's go for the other side of the height.
Let's take all the vertical height and sum it up to 7 because the right side is equal to 7.
So we have 7+7+11
But it's not complete yet.
We are given a dimension 2.
And the 2 is in two places so it's total 2*2= 4
The two is for a small base .
The base is actually an extra to the 11 of the other base.
So summing up
We have 2*11 + 2*7 + 2*2
Perimeter= 22+14+4
Perimeter= 40 units
