To find the length of the base, you must first find the length of the sides, or the value of x. Because it is an isosceles triangle, the legs are equal to each other. 

2x + 4=x + 8
x=4

Now that you have found x, plug it into the equation for the base. 

5(4) - 2
20 - 2

Final Answer: 18

Hope this helps!! :)

For one since since the angles should add up to 180 degrees we must start by adding 55 and 25 which is 80 so 180-80=100 which means c is 100 degrees and for the other I'm going with C

10. The perimeter of a parallelogram is 72 meters. The width of the
nalin [4]

Answer:

Length is 20 meters and Width is 16 meters

Step-by-step explanation:

A parallelogram is a 4-sided figure with 2 pair of parallel sides.

The perimeter is the sum of all 4 sides of the parallelogram.

Let the length of parallelogram be x and width be y.

The perimeter is 72, thus we can write:

x + x + y + y = 72

or

2x + 2y = 72

Also, width is 4 less than length, thus we can write:

y = x - 4

Now, we replace the 1st equation with the 2nd equation and solve for x first. Shown below:

2x + 2y = 72

2x + 2(x - 4) = 72

2x + 2x - 8 = 72

4x = 72 + 8

4x = 80

x = 80/4 = 20

And now y:

y = x - 4

y = 20 - 4

y = 16

Thus, the Length is 20 meters and Width is 16 meters
