Answer:
65 degrees
Step-by-step explanation:
Break the parallelogram up into two triangles. Angle E is 70 degrees and 45 degrees because of the property of equal opposite angles. So E 45 degrees Y 70 degrees and if you add the two up you get 115 degrees. There are 180 degrees in a triangle, so 180-115=65.
To calculate the cost of 1 diesel divide the cost of 5 by 5 to get 1 or $1025/5=205
To get the cost of 17, multiply the cost of 1 which is 205x17=3,485 so 17 is $3,485
Part(A):
To solve the system of Linear equations using Substitution:

Consider the first equation, x+y=7 implies x=7-y













PArt(B): Use a graph to verify your answer to the system:
Using Desmos graphing calculator, graph the two equations.
