Help plsss how do you find the size of angle ABE

∠b = 90°

Step-by-step explanation:

If you wrote it correctly then ∠d will = 90°, right?

We have AB ║(which is parallel to) D => ∠b = ∠d = 90°

P/S: I think that you took the wrong photo, the right question should be above. I'm very please if you can take it again and I will write the right solution down below in the comment section (if u don't mind)

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
