Can someone help me with this proof
maksim [4K]

Step-by-step explanation:

Given :

Given that lines a and b are parallel, angles 1 and 5 are congruent because they are corresponding angles, and angles 1 and 4 are congruent because they are vertical angles

To find : by which property are angles 4 and 5 congruent

Solution :

We know that if two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent.

Also, we know that if two things are equal to the same thing then they are equal to each other . In this case, we can say that if two angles are congruent to a third angle, then they are congruent to each other. As angles 4 and 5 are both congruent to angle 1, they are congruent to each other but angles 4 and 5 are alternate interior angles. So, if parallel lines have a transversal, alternate interior angles are congruent.

N order to write an expression like (5x + 4)3 in expanded form, it helps to look at (5x + 4) as just one number, n.
Vladimir79 [104]

The expression (5x + 4)^3 in expanded form is 125 x3 + 300 x2 + 240 x + 64.  The expression will have also a root of x = -4/5. This is the form of trinomial expansion and can be  solve by multiplying the the term 3 times.
