First you have multiply 6 by both 3x and 8
6*3x = 18x
6*8= 48
18x + 48 + 32 + 12x
now combine like terms
18x + 12x = 30x
48 + 32 = 80
so 30x + 80 is your answer
First find the area of the base, and multiply that by the height. That's the answer.
Area of the base: pi * 3*3 = 3.14*9 = 28.26
Volume of the cylinder: 28.26*8 = 226.08 cubic units
The sum of Supplementary angle =180 degrees
(2x+3)⁰ +(3x+2)⁰=180⁰
adding like terms
5x+5=180
5x=180-5
5x=175
x=175/5 =35 degrees
so the two angles are :
(2x+3)⁰ =2*35 +3 = 73⁰
(3x+2)⁰=3*35 +2 =105+2 = 107⁰
so correct option is D , 73⁰ and 107⁰
