Answer:
sqrt(2) =x
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp/ hyp
sin 45 = x/2
2 sin 45 =x
2 ( sqrt(2)/2) =x
7k -7
-k-(-8k+7)
Distribute the minus sign to all terms in the parentheses
-k--8k-7
Ad negative negative is a positive
-k + 8k -7
Combine like terms
12/w or 12 divided by w
In fraction it is
