I am given an isosceles triangle ABC where the measure of angle b is equal to the measure of angle c. The apex angle is 120 degrees and AB is equal to 10. Find height.
In a similar one the apex angle is 150 with a height of 16. I need to find AB.
I tried using the textbook and class notes but I still do not understand these problems.
Any help is greatly appreciated!
The second is more fiddly as you have 15,75,90 triangles but essentially the same
