(10x-15) find x from the angles

Step-by-step explanation:

You can see the angle opposite to (10x-15) is equal because it is a corresponding angle (learn about them or ask)

The corresponding angle of 10x-15 is 90

so

10x-15=90

now this is simple algebra

10x=90+15

10x=105

x=105/10

x=10.5

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
