Answer:
b = 53
c = 53
Step-by-step explanation:
Alright so we already know that b and c are going to have the same angle measures. We can find b by subtracting 180 degrees to 127. Why you may ask? Its because when b and 127 are added together its obvious that it creates a straight line (supplementary angle). This means that two angles will sum up to 180 degrees. We can create an easy equation and solve for b.
127 + b = 180
b = 53 and c = 53
Best of Luck!
Answer:
9.75
Step-by-step explanation:
let's call G the intersection point of EF & BC.
according to the thales' theorem:

and EF= EG+GF=EG+3




length of the altitude of △AED=EF
EF=EG+GF=1.5+3=4.5
Multiply the top by 10 and the bottom by 1000. So you'll have 12/3 which is 4. Then divide 4 by 10,000 = 0.0004
