Answer 1

Answer:

angle ACE = 80°

angle ACB = 65°

angle ABC = 35°

Step-by-step explanation:

(i) angle BAC = 80°

If CE||BA,

then, AC is the transversal

so,

angle BAC = angle ACE (alternate interior angle)

80° = 80°

angle ACE = 80°

(ii) angle ACB = 180° - (80°+35°) (linear pair of equation)

= 180° - 115°

= 65°

angle ACB = 65°

(iii) angle ABC = 180° - (80°+65°)

= 180° - 145°

= 35°

angle ABC = 35°
