Answer:
is the resulting expression after grouping
Step-by-step explanation:
Given:

Now taking common
from 1st 2 numbers and and 3 common from last we get

Now taking x-3 common from both numbers we get
which is the final equation after grouping
Answer:
No solution.
Step-by-step explanation:
Given

Find all possible solutions
If
, then the triangle is right-angled and the hypotenuse is at b
Given that 
This implies that a > b
In a right-angled triangle, the hypotenuse (side b) is the longest.
Since this is not true for the given sides, then the triangle has no solution.
1 and 8 should be the answer I believe.
Go to where 30 degrees is on the unit circle and find the y-coordinate. That is sin30.
