someone explain…

in  the triangle the length of side b is 7 the m<A= 60 .find the exact length of a and c. Exact means that you cannot give a decimal. You will need to give either an integer, a fraction or a radical 

 

i will need to label the triangle and all work for finding missing sides there will be two separate equations that you solve circle your final answer

You are missing a piece of info. Must have 3 parts of the triangle in order to solve. Could it be that it is a right triangle?

Sierra, did you try to draw and label the triangle? Is there a diagram that goes with your question? Can you simply state what kind of triangle you are referring to? In a previous post you said you could not upload a diagram if it is just a Right Triangle, then your problem was solved correctly by another tutor, using the 30 60 90 right triangle and the relationship of its sides.

You cannot solve a triangle knowing only one angle and one side.


Therefore, this must be assumed to be a right triangle with angle C = 90 deg. Especially because they want exact answer as radicals.


So that makes angle B = 30 deg.


Since the given side b is opposite the 30 deg angle, that makes hypotenuse c = 14 and the side opposite the 60 deg angle a = 7radical3.
