Answer:
Approximately mMK is 53 degrees
Step-by-step explanation:
Here, we want to find the length of MK
As we can see, we have a right triangle at LNK
so
let us find the angle at L first
9 is adjacent to the angle at L and also, 15 is the hypotenuse of the angle at L
so the trigonometric identity that connects adjacent to the hypotenuse is the cosine
It is the ratio of the adjacent to the hypotenuse
So;
cos L = 9/15
L = arc cos (9/15)
L = 53.13 degree
Approximately, L = 53 degrees
so now, we want to get the arc length MK
We are to use the angle-arc relationship here
Using this; arc length MK is equal to the measure of L at the center which is 53 degrees
Answer:
Cuanto dinero voy a pagar 24 $
Cuanto recibiré de cambio 76 $
Step-by-step explanation:
Mis compras son:
1 lápiz 3,50 $
2 plumas 7,90 $
1Libreta 12,60 $
Lo que quiere decir que compre:
3,50 + 7,90 + 12,60 = 24 $
Si cancelo mis compras con un billete de 100 $ me tienen que dar vuelto por:
100 $ - 24 $ = 76 $
