Answer:
see below
Step-by-step explanation:
<2 and <3 are same side interior angles
Since p and q are parallel, <2 and <3 add to 180 ( or are supplementary)
This expression is a perfect square trinomial. It has two answers but they don't have to be different. In this case it has to be the same - because it is a perfect square trinomial.
Plug it into desmos graphing calculator and you'll get A(6,2)

Answer:
Y ≈ 59.0°
Step-by-step explanation:
Using the Cosine rule
cosY = 
with x = 22, y = 20, z = 18
cosY = 
= 
= 
, then
Y = 
( ) ≈ 59.0° ( to the nearest tenth )
