I belive
ED=38
Ea=142
BDC=142
1. x= 27.6
2. x= 41
3. x= 30.2
I'm not sure what the triple thing is but hoped I helped with the other stuff.
Answer:
c2 = a2 + b2
plug in the values, and you get 42 cm.
Answer:
50 degrees
Step-by-step explanation:
The sum of the interior angles of a triangle is 180. We can find the missing angle of the triangle by subtracting out the two measurement of the triangle that we know from 180.
180 - 31 -19 = 130
This angle would be the alternate exterior angel to the parallel line QP. That angle is supplement to the angle that you are looking for. <QTP would be 50 (180 -130)
