Cette question est incomplète.

Question complète

Exercer:

En face, [MH] est une hauteur du triangle MAT.

a.Calculer MH, puis HT.

b. Eva dit: "".

A-t-elle raison? Expliquer.

MA = 7,8cm

MT = 7,5cm

AH = 3cm

Answer:

La réponse d'Eva est incorrecte

Step-by-step explanation:

Nous résolvons les questions abive en utilisant le théorème de Pythagore

c² = a² + b²

a) Application de la formule ci-dessus:

Étape 1

Trouver MH

MA² = MH² + HA²

7,8² = MH² + 3²

MH² = 60,84-9

MH² = 51,84

MH = √51,84

MH = 7,2 cm

Étape 2

Résoudre pour HT

MT² = MH² + HT²

7,5² = 7,2² + HT²

HT² = 56,25 à 51,84

HT = √4,41

HT = 2,1 cm

b) La formule pour le périmètre du triangle MAT =

MA + MT + AH + HT

= 7,8 + 7,5 + 2,1 + 3 = 20,4 cm

Le périmètre du triangle MAT est de 20,4 cm

Donc, la réponse d'Eva est incorrecte
