Answer:

c=0

Step-by-step explanation:

ATQ a.b=|a||b|sin(45)

1+c=sqrt(1+c^2)*sqrt(2)*1/sqrt(2)

1+c=sqrt(1+c^2)

(1+c)^2=(1+c^2)

11Alexandr11 [23.1K]

Answer:

3, 12

Step-by-step explanation:

"x" is the larger number,

"y" is the smaller number.

x + y = 15

x / y = 4

manipulate the equations for the problem

x / y = 4

*y        *y

x = 4y

solve the system of equations by the methord of substitution:

x + y =15

4y + y = 15

5y = 15

y = 3

Subsitute back into the equations given.

x = 4y

x = 12
