Question

I really need help with this Triangle problem. ​

Answer 1

x = 10

y = 20

Explanation:

`\tan \: 30 \degree = (x)/(10 √(3) ) \\ \\ (1)/( √(3) ) = (x)/(10 √(3) ) \\ \\ √(3) x = 10 √(3) \\ \\ x = (10 √(3) )/( √(3) ) \\ \\ x = 10 \\ \\ \cos 30 \degree = (10 √(3) )/(y) \\ \\ ( √(3) )/(2) = (10 √(3) )/(y) \\ \\ y = 10 √(3) * (2)/( √(3) ) \\ \\ y = 10 * 2 \\ \\ y = 20`
