What is the answer??
Amanda [17]

Answer:

angle 1= 104                angle 2= 76

Step-by-step explanation:

angle 1 equals x+66 and angle 2 equals 2x so you set up an equation where they are the sum of 180 degrees because the angles are supplementry angles.

x+66+2x=180                        set the sum of the angles to 180

3x+66=180                            combind like terms

3x=144                                   subract 66 from both sides

x=38                                      divide 3 from both sides

Now you put x back into the measurments

angle 1= (x+66)                              angle 2= 2x

              (38+66)                                           2×38

angle 1= 104                                   angle 2= 76

Or after you know angle 1 you can subtract angle 1 from 180 to get angle 2.

It’s 3 loads and $195 because you multiply 52 by 2 to get the total amount of bricks and then you divide 104 by 45 and you have a remainder of 14 which would be the last load and then divide 65 or whatever the price of the load of bricks to get 195
