<em>Answer</em>
B) y = 3
<em>Step-by-step explanation</em>
Given the system of equations:

Isolating x from equation 1:

Substituting equation 3 into equation 2 and solving for y:

to make the proportion we make the ratio of the similar sides
For example
4/8 = 12/x
or we can write it as 4/12 = 8/x
or 12/x = 4/8
So last option is correct

Answer:
Step-by-step explanation:
Area =6*6sin56/2=18sin56
Area=5.7*6sinx/2=5.7*3 sin x
18sin56=3*5.7sinx
sinx=6sin56/5.7=1.05 *sin 56
Please do the calculation because now I can not do.
I hope it will help you !
