Answer:
x = 4 and y = 8
Step-by-step explanation:
This is a special right triangle with angle measures 90-60-30 degrees
The side lengths are like the following :
The side length that sees 90 degrees is represented with a
The side length that sees 60 degrees is represented with a
The side length that sees 30 degrees is represented with 2a
now, the angle measure that sees 60 degrees is given as 4 so we understand that a is = 4 that's how we find the value of x and y
