∠1 and ∠2 are alternate exterior angles where transversal BE crosses parallel lines AC and DF, therefore they are equal. ∠2 and ∠3 are opposite angles of a parallelogram, therefore they are equal.

... ∠1 = ∠2

... 3x -5 = 2x +15 . . . . substitute the given values

... x = 20 . . . . . . . . . . . add 5-2x

The measures of angles 1, 2, and 3 are 2·20+15 = 55 . . . degrees.

How do you do elimination in systems of equations?
VMariaS [17]
Well, for solving system of equations, we can use either substitution where we plug one equation into the other, or elimination where we combine the equations.


- Using elimination, you would to eliminate one variable from both equations, so you automatically would get one equation with one variable!

Solve −2x2 − 16x − 44 = 0.
Ksivusya [100]

Answer:

x=-3

Step-by-step explanation:

-2x2=-4

-4-16x-44=0

combine like terms (-4,-16)

-48-16x=0

move the 16x to the other side of the equal sign (add 16 since its -)

-48=16x

you need x alone so you need to divide by 16
