Answer:
x = 6
y = 6

z = 12
Explanation:
the ratio of sides in a 30-60-90° triangle is, respectively, 1 :
: 2
therefore, 'x' must have a measure of 6
which means the hypotenuse must have a measure of 12
other triangle is a 45-45-90° triangle whose sides are in a ratio of 1 to

this means that 'y' must be 12/
which is 6

'z' must be 6

= 12
