Find the value of x. Then find the angle measures of the polygon.

x° = 125°

(x+10)° = 135°

Step-by-step explanation:

Given:

Sum of measures of angle = 720°

Solution:

We know that:

Sum of measures of angle = 720°

120 + 100 + 120 + x + 10 + 120 + x = 720

x + x + 120 + 100 + 120 + 10 + 120 = 720

2x + 470 = 720

2x = 720 - 470

2x = 250

Divide both sides by 2

x = 250/2

x = 125

Now,

Angles measures

x° = 125°

(x+10)° = (125+10)° = 135°

Hope this helped!

there are no short passages to look at

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
