Omg help me please like I just can't right now <br><br> 2x-6y= -12 <br> x+2y=14
steposvetlana [31]

here,

2x-6y= -12

2(x-3y)= -12

x-3y = -6...........eq1

x+2y=14............eq2

we can subtract the above two given equations

we get,

x - 3y =  - 6 \\ x + 2y = 14

___________

- 5y =  - 20

so,

y=4

now to find the value of x we have to substitute the value of y in any of the above two equations, I choose eq2

we get,

x + 2y = 14 \\ x + 2 \times 4 = 14 \\ x + 8 = 14 \\ x = 14 - 8 \\ x = 6

<h3>so,</h3><h3> x=6,y=4</h3>

For an acute angle θ, the equation sin (θ) = cos (7°)is true. What is the value of θ?
8_murik_8 [283]

Answer:

  θ = 83°

Step-by-step explanation:

For acute angles, the sine of an angle is the cosine of its complement, and vice versa.

__

  sin(θ) = cos(90° -θ) . . . . relation between sine and cosine

  sin(θ) = cos(7°) . . . . . . . . given

  90° -θ = 7° . . . . . . . . . matching arguments of cos( )

  θ = 83° . . . . . . . . . add θ -7° to both sides
