Angles on a straight line add up to 180 degrees so

45 + 3x = 180
Subtract 45 from both sides to remove the 45 on the left

3x = 135
Then divide both sides by 3
x = 45

Answer is X = 45

Answer:

45 + 3x = 180

x = 45

Step-by-step explanation:

45 + 3x = 180

3x = 180 - 45

3x = 135

x = 135/3

so, x = 45

Amanda wants to make a rectangular fenced area for her dogs. She wants the area to be 32 square feet with the length of the yard
navik [9.2K]
The fence is a 8x4 fence as they multiply up to 32 square feet and 8 is double 4. If you add 8+8+4+4 you will get 24. Then you multiply the perimeter (24) by 3 to get the final cost. This means that the final cost will be $72.00.
