Apply the Law of Sines.
sinB/b = sinA/a
sinB/3 = sin(30°)/2
sinB = (3/2)sin(30°) = 0.75
Therefore
bsinA = 3*sin(30) = 1.5
0.5b = 0.5*3 = 1.5
Answer:
There is exactly one triangle because b sinA = 0.5b.
I believe the answer is C) 0
No it is not a right angle
Consider this option:
1. area_rombus=a*h, where a=6 - the length of the side, h - height.
h=area_rombus/a.
2. area_sq=a², where a=6 - the length of the square.
area_sq=36, area_rombus=4/5 *36=28.8.
3. according to the item 1 h=area_rombus/a=28.8/6=4.8.
answer: 4.8
