HELP MATH ANSWER QUESTION

Answer 1

x = 84 , y = 168

Explanation:

`Sin 60 = (opposite side)/(hypotenuse)\\\\ (√(3))/(2)= (AB)/(BC)\\\\ (√(3))/(2) = (84√(3))/(y)\\\\Cross\ multiply ,\\\\y*√(3) =2*84 √(3)\\\\y= (2*84*√(3))/(√(3))\\\\y=168`

`Cos\60 = (adjacent)/(hypotenuse)\\\\ (1)/(2)= (AC)/(BC)\\\\ (1)/(2)= (x)/(168)\\\\ (1)/(2)*168=x\\\\x= 84`
