Step-by-step explanation:
In given rt.angled triangle,
Sin thita =p/h
=26.1/28.7
=0.9094
So correct answer is option D.
All the options are incorrect, if you're talking about circle! which is most common

Answer:
(-5, -10)
Step-by-step explanation:
y+2x = 5y
==>2x=4y
x=2y
5y=3(2y)+5
==>
y = -5
x = -10
==>
one solution
Factor out 12x^3y^2
12x^3y^2(3y^2+5x^ 2 y z^2 -1)
