Since you have an angle and at least one side you can use either sine, cosine or tan. For this question, you would use sine like above. Hope this helps!
Answer:
Step-by-step explanation:
X^2=-y^2+10y+5
Yo sup??
by Pythagoras theorem we can say that
DE²=3²+2²
=9+4
DE=√13
=3.60 units
angle D=tan-1(2/3)
=33.7
angle E=tan-1(3/2)
=56.3
Hope this helps
