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