19. Complete the paragraph proof Given: ∠1 and ∠2 are supplementary. and ∠ 2 and ∠3 are supplementary
Prove: ∠1≅∠3

By definition of supplementary angles, m∠1+ m∠2 =_
(b). Then, m∠1 + m∠2 = m∠2 + m∠3 by the_
(c). Subtract m∠2 from each side. You get m∠1=_(d), or ∠1 ≅
(e).

you never say the total so we cant find the percentage used for petrol
