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
The answer would be D. line of symmetry because he lines stay even and never cross eachother.
Answer: The answer is 180 degrees
If u were to add 5x+20=9x you’d get x=5
