Answer:
x=5√3 units
y=10 units
Step-by-step explanation:
tan 30°= 1/√3
here ,tan 30°=5/x
therefore,
1/√3=5/x
or,x =5√3....(i)
sin30°=1/2
here,sin 30°= 5/y
therefore
1/2=5/y
or,y=5×2
or,y=10.....(ii)
from (i) and (ii),we get the values of x and y
hope it helps

sin30=5/y
1/2=5/y
y=10
by pythagoras theorem
y^2=x^2+(5)^2
10^2=x^2+25
100-25=×^2
x^2=75
x=5×3^1/2
