Answer:
Para poder definir los radianes, es necesario introducir el concepto de ángulo central. Un ángulo central es un ángulo cuyo vértice está en el centro de un círculo. En el círculo siguiente, el centro es el punto O, la longitud del radio es r, y es el ángulo central y 30 grados equivale a vil.
Step-by-step explanation:
Answer:
a and d
Step-by-step explanation:
210/= 30 so the answer is 30
2/3 ÷ (-5/6)
When dividing fractions, all you really have to do is multiply the first fraction by the second fraction's reciprocal.
Remember, a reciprocal is the fraction/whole number flipped.
Ex : 4/6 turns into 6/4
So, the reciprocal of -5/6 is -6/5
Therefore, our new equation looks like this :
2/3 × -6/5
Multiply the numerators with the numerators, and the denominators with the denominators :)
Numerators : 2 × -6 = -12
Denominators : 3 × 5 = 15
SO, our answer is -12/15
Simplify this.
-4/5

Step-by-step explanation:
The distance from point P to QS is the distance from point P (1, 1) to the point of interception R(-3, 5).
Use distance formula to calculate distance between P and R:

Let,
