Can you someone me with this idk if it’s correct

x = 30

Step-by-step explanation:

In a parallelogram, opposite angles are CONGRUENT (they are equal).

If we draw a parallelogram ABCD, we will see that:

Given B = 60 and D = 2x >>> we also know they are Equal. So we can say:

B = D

60 = 2x

Now we solve for x:

2x = 60

x = 60/2

x = 30

which expression represents the approximate length of bc?

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
