By the law of cosines, the angle $C$ satisfies

$8.77^2=2^2+9^2-2\times2\times9\times\cos C$

which reduces to

$\cos C=0.2246\implies C=\arccos(0.2246)\approx1.34422\text{ rad}$

which converts to approximately 77 degrees (this can be done my multiplying by 180 and dividing by pi).

Solve for all values of x (x+9)2=4

serg [7]

Answer:

x = -7

Step-by-step explanation:

you have to distribute the 2 to what is in the parenthesis, then you get left with 2x+18=4 so subtract the 18 from both sides leaving you with 2x=-14 so you divide both by 2 leaving you with x=-7.
