Answer:
256 diputados
Step-by-step explanation:
Paso 1
Encontramos la fracción de diputados que vota en blanco
Sea fracción total de diputados = 1
Fracción de diputados que vota en blanco = x
5/8 de los diputados votaron a favor.
= 1 - 5/8 = 3/8
3/4 del resto de diputados votaron en contra, de ahí:
= 3/4 de 3/8
= 9/32 votaron en contra
1 = 5/8 + 9/32 + x
x = 1 - (5/8 + 9/32)
x = 1 - (20+ 9/32)
x = 1 - 29/32
x = 3/32
Paso 2
Número total de diputados presentes =
3/32 × x = 24
3 veces / 32 = 24
Multiplicar en cruz.
3x = 32 × 24
x = 32 × 24/3
x = 256 diputados
De ahí que estuvieran presentes 256 diputados

Step-by-step explanation:
Answer: Line AB = 5.2
Step-by-step explanation: We start with triangle ACD, with two sides given and angle A which shall be the reference angle can be calculated as,
SinA = opposite/hypotenuse
Where the opposite is 4.3 (line facing the reference angle) and the hypotenuse is 5.6 (line facing the right angle)
SinA = 4.3/5.6
SinA = 0.7679
By use of a calculator or a table of values
A = 50.17 degrees.
Having been told that both angles DAC and BAD are equal, then we move to triangle ADB where the reference angle is 50.17 (BAD) and the opposite is 4 (line facing the reference angle) and the unknown side is the hypotenuse (line AB).
Sin 50.17 = opposite/hypotenuse
Sin 50.17 = 4/AB
0.7679 = 4/AB
By cross multiplication we now have
AB = 4/0.7679
AB = 5.2090
Approximately to one decimal place,
AB = 5.2 units
