Find the value of x and the value of y.

if this is trigonometry, then x= 15 and y = 8.7 (1 d. p)

Step-by-step explanation:

use the three trig ratios as in sine , cosine and tangent.

To do this, first identify the sides so y is the adjacent, x is the opposite side and 10√3 is the value of the hypotenuse.

In this case, use sine and tangent :

sin 60=x/ 10√3

x = sin 60 * 10√3

x = 15

tan 60 = 15 /y

y = 15/ tan 60

y = 8.7 (1 d.p)

1760 kilometers

step-by-step explanation:

multiply the amount of time the plane took to travel by it's speed

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
