Degger [83]

Answer:

b ≈ 2.7

Step-by-step explanation:

The missing angle A is ...

A = 180° -53° -80° = 47°

The law of sines tells you ...

b/sin(B) = a/sin(A)

b = sin(80°)×2/sin(47°) ≈ 2.6931

Side b is about 2.7 units.

Solve the system of linear equations by substitution

ziro4ka [17]

$y - x = 0 ...equation 1$
$2x - 5y = 9 \: ...equation \: 2$
working with equation 1
$y = x \: ...equation \: 3$
next subsitue equation 3 in equation 1
$2x - 5(x) = 9$
$2x - 5x = 9$
$- 3x = 9$
divide by -3
$x = - 3$
substitute x= -3 in equation 1
$y - ( - 3) = 0$
$-(-3) = + 3$
$y = - 3$
