Dans chaque cas écrire l'égalité de Pythagore : a) BON est un triangle rectangle en N? b) FIL est un triangle rectangle en I?

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz

the bottom of the spinner is not flat.

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
