The mean to your question is 62.3
you need to add all of the numbers together and then divide by how many numbers are there to find the answer.
The base angles are both equal to (180-70) / 2 = 55 degrees
and 1/2 base = 123
so we have tan 55 = a / 123 where a = altitude
a = 123 * tan55 = 175.66
I think 45 because if you look at the top of the other 45 the graphs look the same lengths except this one stretches out so 45°
