Answer:

x = 111

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 7 , then

sum = 180° × 5 = 900

Sum the interior angles and equate to 900

x + 139 + 121 + 125 + 126 + 158 + 120 = 900

x + 789 = 900 ( subtract 789 from both sides )

x = 111

Answer:

a=5,b=10,c=15

1)(a+b)-5(c+a)

=(5+10)-5(15+5)

=(15)-5(20)

=15-5(20)

=10(20)

=200

2)(10×15)10(5×2)

=150×10×10

=15000

3)(a-b)+(a+b)

(5-10)+(10+5)

(-5)+15

-5+15

=10

4)(2ab-45)+a

=(2×5×10-45)+5

=(100-45)+5

=55+5

=60
