Answer:

  x = 6

Step-by-step explanation:

The two angles are marked as being equal, so the line down the middle of the triangle is an angle bisector. An angle bisector divides the sides of the triangle proportionally, so you can write the proportion ...

  x/12 = 5/10

  x = 12(5/10) . . . . multiply by 12

  x = 6

Factor 28+56t+28w28+56t+28w28, plus, 56, t, plus, 28, w to identify the equivalent expressions. Choose 2 answers:
Effectus [21]

Answer: The factorization of  28+56t+28w =28(1+2t+w)

The factors of 28+56t+28w are 28 and 1+2t+w.

Step-by-step explanation:

The given expression : 28+56t+28w

To factorize it, we need to find the common factor.

As 56 can be written as 2 x 28.

So, the above expression would become

28+2\times28t+28w

Now, taking 28 as common from all the terms, we will get

28(1+2t+w)

Thus, the factorization of  28+56t+28w =28(1+2t+w)

And the factors of  28+56t+28w are 28 and 1+2t+w.
