Answer 1

Answer:

Step-by-step explanation:

180-100=80

50+80+x=180        (sum of angle in a triangle is 180)

130+x=180

x=180-130=50

Answer 2

Step-by-step explanation:

extend CD to intersect EA at point F

FD ll AB

angle EAB =50°

therefore angle EFD = 50°

angleEFC=50°(F-C-D)

angle ECF=180-100(linear pair of angles)

angleECF=80

in triangle EFC

angles E+ F+C= 180°

sum of angles in triangle

x+50+80= 180

x+130=180

x=180-130

= 50°

the value of x is 50°

hope it helps you!!!
