No they have they same angle measure APEX
-468
Explanation: Substitute in the numbers for the variables presented. I’ve shown it step-by-step in the photo below.
Answer and Step-by-step explanation:
When making a perpendicular line, you take 2 points on a straight line.
- You put the compass on the two points, making marks above and below to be able to draw the line.
When making an angle bisector line, you use the angle and 2 points to make a straight line that will bisect the angle.
- You put the compass on the angle, making an arc from the two lines that join to make the angle. Then, you put your compass on where the arc meets the lines, and make a mark, which you then draw a line through.

Answer:
Definamos R como la "velocidad" a la que una persona puede construir la barda dada.
Supongamos que la persona necesita un tiempo T para construir la barda, entonces tenemos la relación:
R*T = 1 barda.
Si dos personas trabajan juntas la velocidad de trabajo va a ser (R + R), y sabemos que ellos pueden completar el trabajo en 2 días, entonces:
(R + R)*2 días = 1 barda
(2*R)*2 días = 1 barda
(2*R) = (1/2) barda por día
R = (1/2)*(1/2) barda por día = (1/4) barda por día.
Esto significa que una persona puede completar un cuarto de la barda en un día de trabajo.
Ahora queremos saber cuantas personas se necesitan para construir una barda en solo medio día, entonces debemos resolver:
(N*R)*0.5 días = 1 barda
Donde N es el número de personas que queremos obtener.
(N* (1/4) barda por día)*0.5 días = 1 barda
N*(1/4) barda por día = (1/0.5) bardas por día = 2 bardas por día
N = 2/(1/4) = 2*4 = 8
N = 8
Se necesitan 8 personas para construir una barda en medio día.
Answer:
The age of the spear head is of 1938 yers.
Step-by-step explanation:
The amount of carbon 14 after years is given by the following equation:
In which Q(0) is the initial amount and r is the decay rate.
The half life of carbon 14 is 5700 years.
This means that 
So
So
We have to find:
t for which Q(t) = 0.79Q(0). So
Rounding to the nearest year.
The age of the spear head is of 1938 yers.
