Which triangle has an obtuse angle? ​

Answers

Answer: I cant see that last answer but I think it would be that one

Step-by-step explanation:

(Redirected from Obtuse triangle) An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles.

Hope this helps if it did pls mark me brainiest

none of them

an obtuse angle is called to an wngle which is more than 90° and less than 180°

none of these have such an angle

Answers

Answer:

I believe it is 2 grams.

Step-by-step explanation:

there are 1000 grams in 1 kg, there are 500 crayons, therefore each crayon weighs 2 grams

2 grams

1 kg = 1000 g
1000 / 500 = 2g

if f(x)=3, what is f(4)= ?

Answers

Find the following arc measures.

Answers

Answer:

Arc KL [tex]=23[/tex]

Arc OM [tex]=113[/tex]

Step-by-step explanation:

We know that Angle NPM is equal to 90 degrees.

Therefore, Angle KPM is also equal to 90 degrees.

We are told that Arc LM is equal to 67.

Thus, the measure for Arc KL is equal to [tex]90-67=23[/tex]

We also know that Angle OPN is equal to Angle KPL.

Therefore, the measure of Arc ON[tex]=23[/tex]

Using that information, we know that Arc OM is equal to [tex]90+23=113[/tex]

Step-by-step explanation:

Perhaps you want n for ...

You know that multiplying by 10 appends a 0 to the right end of an integer number. So, a 1 with 6 zeros has been multiplied by 10 six times. The exponent signifies the number of times the factor is repeated. The exponent, n, is 6.

Could somebody solve it, explaining it?

Answers

Answer:

a=44, b= 58

Step-by-step explanation:

You look at the first triangle that gives you the two angles, and with the rule that every triangle's angles inside it need to add up to 180 degrees, you can determine that the missing angle is 46 degrees, which translates over to the other triangle, meaning that a would be 44 degrees.

The other triangle has two identical angles, being 61 degrees, which helps translate to the smaller triangle, again allowing you to infer that b is 58 degrees

.- Sí 159.6 gramos de Fe2O3 liberan 67.2 litros de CO2 ¿cuántos litros de CO2 se liberan si reaccionan 45 gramos de Fe2O3? de acuerdo a la siguiente reacción: Fe2O3 (s) + 3 CO (g) 2 Fe (s) + 3 CO2 (g)

Answers

Answer:

45 g de oxido de hierro (III) liberarán 18.9 L de CO₂

Step-by-step explanation:

La reaccion quimica es la siguiente:

Fe₂O₃ (s) + 3CO (g)  →  2Fe (s) + 3CO₂ (g)

1 mol de oxido de hierro (III), reacciona con 3 moles de monoxido de carbono para liberar 3 moles de CO₂ y 2 moles de Fe sólido.

Pasamos la masa de F₂O₃ a moles:

159.6 g . 1 mol /159.7g = 1 mol de oxido

Entonces, aplicamos la regla de tres:

1 mol de oxido produce 3 moles de dioxido de carbono, indudablemente eso será lo que formemos de producto, por lo tanto 3 moles de CO₂ estan ocupando 67.2 litros.

Ahora calculamos los nuevos moles:

45g . 1 mol /159.7 g = 0.282 moles

Aplicamos la regla de tres:

Si un mol de oxido produce 3 moles de CO₂

0.282 moles producen (0.82 . 3 ) = 0.845 moles de CO₂

Como tenemos menos moles de gas, el volumen ocupado sera mayor, hacemos la regla de tres:

Si 3 moles de CO₂ ocupan 67.2 litros

0.845 moles ocuparan (0.845  . 67.2/  3 ) =  18.9 litros
