Answer:
1.6
Step-by-step explanation
You can use the angles given to figure out the degree of the angles given and then with that you set up your equation as v divided by Sin(16) is equal to 5.8 divided by sin(87) and cross multiply.
After you cross multiply you should get approximately 1.5987 is equal to v times sin(87)
you then fin out the approximation of sin(87) which should be around 0.9986 and divide both sides by 0.9986 so v is alone and your answer comes out to be v = 1.6

Answer:
Step-by-step explanation:
We have been given the equation:
And 
Second equation can be rewritten as:
We will solve the equations:
(1)
(2)
Multiply equation (1) by 5 and equation (2) by 3 we get:
(3)
(4)
Now, subtract (4) from (3) we get:
Now substitute in equation (1) we get:
No not all squares are congruent to each other they all have longer sides than others
X=-2 + y
X=5y-4/3
