Step-by-step explanation:
ABC is an isoceles triangle (both legs are equally long). and AB is its baseline.
OC is now a median for ABC splitting the angle at C and AB in half.
so, we have 2 right-angled triangles : OAC and OBC.
the half-angles at C are 42/2 = 21°.
the angles at A and B are 90°.
and the half-angles at O are 180 - 90 - 21 = 69°.
remember that the sum of all angles in a triangle must always be 180°.
AB are the heights of both of these triangles.
the single height is sin(69)×7 = 6.535062985... cm
and so,
AB = 2× height = 13.07012597... cm.

What's the question?
Step-by-step explanation:
Michael owns a small paper company called Michael Scott Paper Co. He has 5 clients and needs to sell them each a specific amount of paper. They have each ordered 3 3/10 worth of boxes. He has to find out how many paper boxes he has to sell and how much extra paper (in tenths) he has total.
IF you want to turn it into a question, add:
How many paper boxes is he selling?
A) (2+2)times3 because you will have to distributive properties,
