Answer:

x = 105

Step-by-step explanation:

Sum of n-sided polygon = (n - 2)*180

The polygon given is a 7-sided polygon, therefore substitute n = 7 into (n - 2)*180

Sum of the polygon = (7 - 2)*180 = 900°

Thus:

x + 102 + 165 + 123 + x + 11 + 128 + 161 = 900

Add like terms

2x + 690 = 900

2x = 900 - 690

2x = 210

x = 210/2

x = 105

Please help!! If y = sin x, then dy/dx =
Citrus2011 [14]

Answer:

the answer is option B

Step-by-step explanation:

To find dy/dx the equation here is

first multipled by derivative of second + second multipled by derivative of first

y = x*sinx

dy/dx = x * derivative of sinx + sinx * derivative of x

derivative of x with respect to x is 1

derivative of sinx with respect to x is cosx

therefore

dy/dx = x * cosx + sinx * 1

= x * cosx + sinx

In the first quadrant you start at (7,3) and move 5 unit left
AveGali [126]

Answer:

That would be (2,3)

Step-by-step explanation:

When we're moving left in the coordinate plane, we are subtracting the x-coordinate by how much distance we move.

In this case, 7-5=2, so the new x-coordinate is 2, but the y-coordinate doesn't change since we're going horizontally and not vertically.
