Step-by-step explanation:
Answer:
V= 21.7
Step-by-step explanation:
180-90=90
2v+v+25=90
3v+25=90
3v=65
V=21.7
Calculation of x:
we can see that
x is hypotenuse
so, we can use pythagoras theorem


Calculation of y:
we can use tan formula to find it
opposite=8
adjacent=10



Calculation of z:
we know that sum of all angles of any triangle is 180
