Step-by-step explanation:

right triangle is A right triangle or right-angled triangle is a triangle in which one angle is a right angle
acute triangle is An acute triangle is a triangle with three acute angles. An obtuse triangle is a triangle with one obtuse angle and two acute angles
obtuse triangle is An obtuse triangle is one that has an angle greater than 90°. Because all the angles in a triangle add up to 180°, the other two angles have to be acute (less than 90°). It's impossible for a triangle to have more than one obtuse angle.

The base of a triangle is....

nataly862011 [7]

Answer:

$a=49$

Step-by-step explanation:

You would solve this the same way you would with any other triangle problem. You will plug in for the base and the height in this formula $a=\frac{1}{2}bh$ .

$a=\frac{1}{2}bh\\a=\frac{1}{2}(\sqrt{343})(\sqrt{28})$

Now we will multiply the two radicands.

$a=\frac{1}{2}\sqrt{9604}$

For this we will split the 9604 into 49 and 196.

$a=\frac{1}{2}\sqrt{49}\sqrt{196}$

Now we just take the square roots of those two and since they're perfect squares they'll be whole numbers.

$a=\frac{1}{2}(7)(14)$

Next we just multiply everything together.

$a=49$

Bonjour, pouvez vous m'aidez svp ^^ Ci-contre, [MH] est une hauteur du triangle MAT. Éva affirme que le périmètre du triangle MA

Anna35 [415]

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

Answer:

$x {}^{2} = 150$

Step-by-step explanation:

What I did was

$5 \times 5 = 25$

then I did

$5 \times 5 = 25 \times 5 = 150$

and I'm hoping 150 is the answer. HOPE THIS HELPED

What value should go in the empty box to complete the calculation for finding the product of 62.834 × 0.45? A)2,213,360 B)2,313,

Aleonysh [2.5K]

Answer:

28.27530

Step-by-step explanation:

Given the expression 62.834 × 0.45, to solve this expression, first we need to convert it to fraction

62.834 = 62834/1000

0.45 = 45/100

Take the product if the resulting fraction:

62.834 × 0.45 = 62834/1000 × 45/100

= (62834×45)/1000×100

= 2,827,530/100,000

= 28.27530
