Answer:
<1 : 36 degrees
<2 : 90 degrees
<3 : 36 degrees
<4 : 54 degrees
Step-by-step explanation:
First off, rhombus's have right angles formed at the middle, meaning that <2 is 90 degrees. Then, it's given that angle is 54 degrees, and its alternate interior angle is the one that is adjacent to <3. To find <1, add 90 and 54, and subtract that from 180. So <1 is 36 degrees. So that automatically makes < 3, 36 degrees and < 4, 54 degrees.
First find slope
(2-4)/(3+1) = -2/4 = -1/2
Use point (3,2)
y-y1 = m(x-x1)
Plug everything in
y-2 = -1/2(x-3)
Solution: A
