Answer:
C XD
Step-by-step explanation:
The altitude of a triangle goes from the vertex (corner) to the opposite side. It must be perpendicular to the opposite side ( at a right angle)
XD is an altitude
The point-slope form:
We have:
Substitute
34 Deg
Since the Triangle is isoceles, each of the internal base angle = 180-107=73
Sum of internal angles =180, Angle4= 180-(73+73)= 180-146=34
the number that occures the most is the answer
6.6
