Question

Find the value of x and the value of y.

Answer 1

Answer:

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)
