In leftmost triangle:
opposite side =y
adjacent=a
now, we can use trig formula

now, we can solve for y

adjacent=b
opposite=y
a+b=15
b=15-a
now, we can use trig formula

now, we can solve for y

now, we can set them equal
and then we can solve for a




now, we can find b


now, we can use trig formula

now, we can find z

we can simplify it
and we get
