Answer:
angle 3 = angle 7 = 114° ------- because corresponding angles are equal
For x=2, the value of the expression 4(5x–8) is 4 more than the value of the expression 2(4–x)
Step-by-step explanation:
We have to convert the given statement in mathematical or algebraic form to get the value of x for which the given condition is true.
So,
The problem can be written as:

Applying distributive property

Adding 32 on both sides

Adding 2x on both sides

Dividing both sides by 22

Hence,
For x=2, the value of the expression 4(5x–8) is 4 more than the value of the expression 2(4–x)
