I don't know how to solve for the measures of each angle but I can tell what type of angles each of these are. (a) obtuse angle, (b) not sure, (c) not sure, (d) The relationship between the angles BA and BE is that together they form a right angle. And #3, I cannot helps with. Very, sorry that I was not able to answer all of your question. Hope this helps!

Step-by-step explanation:
2 = ⅔[6] + b
4

If you want it in <em>Standard Form</em>:
y = ⅔x - 2
- ⅔x - ⅔x
_________
−⅔x + y = −2 [We do not want fractions in our standard equation, so multiply by the denominator to get rid it.]
−3[−⅔x + y = −2]

_______________________________________________
−5 = 3⁄2[10] + b
15

If you want it in <em>Standard</em><em> </em><em>Form</em>:
y = 3⁄2x - 20
- 3⁄2x - 3⁄2x
__________
−3⁄2x + y = −20 [We do not want fractions in our standard equation, so multiply by the denominator to get rid of it.]
−2[−3⁄2x + y = −20]

* Parallel Lines have SIMILAR <em>RATE OF CHANGES</em> [<em>SLOPES</em>], so ⅔ and 3⁄2 remain the way they are.
I am joyous to assist you anytime.
Your answer should be B. Two sets are equal if they contain the same elements. Two sets are equivalent if they have the same cardinality or the same number of elements.
