Given angle D= 60 degrees, determine the PERIMETER of triangle ABC. Leave answers in exact form (no decimals). Simplify all radicals and
rationalize the denominator. (You may write roots in the following ways:
2root5 or 2r5)

15*(1+root(3))

Step-by-step explanation:

BD=5, BC=5*root(3), you can find it by using trigonometry.

AC^2=300, AC=10*root(3)

AB^2=225, AB=15.

Perimeter of ABC is AB+BC+CA=15+5*root(3)+10*root(3).

15(1+root(3))

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this
