To solve the value of x we use the sine rule that states.
a/sinA = b/sinB = c/sinC
Where a, b, and c are the opposite sides of angle A, B. and C respectively.
x/sin60 = 7/sin80
x =(7sin60)/sin80
= 6.062/0.9848
=6.155696691
To 3 significant figures the answer is 6.16

Answer:
The ordered pair is one of the solution to the system of equations. See below.
Step-by-step explanation:
To tell if the ordered pair is the solution to the system of equations or not, we can do by substituting the ordered pair in both equations.
(x, y) = (5,-6)
Substitute x = 5 and y = -6 in both equations.
<u>First</u><u> </u><u>Equation</u>
6x+3y=12
6(5)+3(-6)=12
30-18=12
12=12
<u>Second</u><u> </u><u>Equation</u>
4x+y=14
4(5)-6=14
20-6=14
14=14
Because both equations have same sides which mean that both equations are true for (5,-6). Therefore (5,-6) is part of the equations.
