Answer:
sum of interior angles of octagon is 1080 degrees
From figure ,
136 + 132 + 129 + 116 + 158 + 141 + 124 + x = 1080
so, x = 1080 - 936
= 144
Step-by-step explanation: Simply add the angles and substract the sum from 1080 which is the sum of interior angles of octagon
The following equations are solved in terms of x:
a) 2x - 3 = y
2x = y + 3
x = (1/2)y + 3/2
b) 2 + 2x - 1 = 4y
2x - 1 = 4y
2x = 4y + 1
x = 2y + 1/2
c) 2A + 4x + 3B = 10
4x = 10 - 2A - 3B
x = 5/2 - (1/2)A - (3/4)B

Answer down below :)
Step-by-step explanation:
The volume of the rectangular prism is:
20 x 9 = 180cm^2
The volume of the triangular prism is
6 x 9 x 1/2 = 27cm^2
I'm sorry, that is all I can do, but the total volume would be 180 + 27 + the cylinder's volume. Have a nice day :)
