Which triangle has an obtuse angle?
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
Step-by-step explanation:
an obtuse angle is called to an wngle which is more than 90° and less than 180°
none of these have such an angle

Find the following arc measures.
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]
Hope I helped!

Step-by-step explanation:
.- 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)
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

Answer: 1ST ONE CUZ THE LINE IS AT A CERTAIN ANGLE AT A POINT TO MATCH THE FIRST ANSWER
Step-by-step explanation:
If are AC is 122 degrees and arc BC is 192 degrees, what is the measure of angle ACB
ACB = AC + BC
ACB = 122 + 192 = 314
The answer is b. 314 degrees
4 x 10" = 4,000,000
n =
9514 1404 393
Answer:
n = 6
Step-by-step explanation:
Perhaps you want n for ...
[tex]4\times10^n=4\,000\,000\\\\10^n=1\,000\,000 \qquad\text{divide by 4}\\\\n=6\qquad\text{count the zeros}[/tex]
__
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.
How many solutions does this equation have? -5(4 - x) = -5x + 20

Could somebody solve it, explaining it?
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

Ross and Ronnie are late for their favorite show . Ross walks around a rectangular park with dimensions of 150 ft by 215 ft. Ronnie decides to cut across the park in a diagonal path. Who walks the shortest distance and by how much? *
Answer:
Ronnie walked the shortest distance by (365 - 262.15 ) = 102.85 ft
Step-by-step explanation:
The image attached represent the rectangular park. In this case, the dimensions are;
AB = CD = 215 ft
AC = BD = 150 ft
Total distance walked by Ross = AB + BD = 215 + 150 = 365 ft
Distance walked by Ronnie = AD
∠ABD = right angle triangle, using pythagoras rules;
AD² = AB² + BD²
AD² = 215² + 150²
AD² = 68725
AD = √68725
AD = 262.15 ft
Distance walked by Ronnie = 262.15 ft
Ronnie walked the shortest distance by (365 - 262.15 ) = 102.85 ft
if f(x)=3, what is f(4)= ?
Answer:
12
Step-by-step explanation:
Since f(x) = 3, you would multiply 3 by 4. This is because you are basically saying that you have 4 x's and each x is equal to 3. 3+3+3+3=12 or 4(3)=12
