Question

Pls help me solve question number 9!!!!

Have my half yearly tomorrow!!

PLZ HELP!?!?!?!?

Answer 1

in triangle EBA angleA<angleE

therefore AB>EB-1

and in triangle BCD angleC>angleD

therefore BD>BC-2

from 1 and 2 we get

AB+BD>EB+BC

therefore, AD>EC

Answer 2

Answer:

exterior angle B+interior angle B=180°(linear pair)

140°+B=180°

B=180°-140°

B=40°

angle A+angle B+ angle C=180°(angle sum property)

let we take angle A and B as x

so,

x+40°+x=180°

2x+40°=180°

2x=180°-40°

2x=40°

x=40/2

x=20°

so other two angles=20°
