Step-by-step explanation:
(a)
Sum the parts of the ratio , 1 + 2 + 3 = 6 parts
Divide sum of angles in a triangle by 6 to find the value of one part of the ratio.
180° ÷ 6 = 30° ← value of 1 part of the ratio
2 parts = 2 × 30° = 60°
3 parts = 3 × 30° = 90°
Since there is an angle of 90° then the triangle is right.
(b)
The shortest side is the side opposite the smallest angle of 30°
Using the sine ratio and the exact value
sin30° = 
, then
sin30° = 
= 
= ( cross- multiply )
2 opp = 19 ( divide both sides by 2 )
opp = 9,5
Shortest side in the triangle is 9.5 cm

Answer: 2 1/5 partes de torta
Step-by-step explanation:
Para contestar esta pregunta debemos sumar cada parte de torta:
0.7+9/12+6/8 =
Convertimos las fracciones en decimales, para tener todos los valores expresados de la misma forma. Dividiendo:
9/12=0.75
6/8=0.75
Sumamos
:
0.7+0.75+0.75 = 2.2 partes = 2 1/5 partes
En conclusión, Carolina y sus amigos comieron 2 1/5 partes de torta.
