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 is number 1. Because 12/10 =20/18 is a true statement. None of the others are true
Answer:
Since the triangles are congruent, AB=ED so AB=14
Angles F is congruent to angle C so F=39 degrees
