Solve for x and y. Write any radical answers as "sqrt( )" or "squareroot( )".

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

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons

its a straight line parallel to the time axis
