Answer:

x = 26

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , then

x + 3x + 5x - 54 = 180 , that is

9x - 54 = 180 ( add 54 to both sides )

9x = 234 ( divide both sides by 9 )

x = 26

Answer:

u = 150

Step-by-step explanation:

Number of vertices:

Find the sum of the interior angles:

180(n - 2)

180(10 - 2)

180(8)

1440

To find u:

u = 1440 - (130 + 145 + 160 + 150 + 130 + 150 + 125 + 155 + 145)

u = 1440 - (1290)

u = 150
