Arc DB = 2 ( angle DAB ) = 2 (35) = 70 degrees
Arc DG = 2 (Arc DB) = 2 (150) =150 degrees

Arc DAG = 360 - Arc DG = 360 - 150 = 210 degrees

Angle DCG = (210 - 150) /2 = 30 degrees
Angle DCB = 30/2 = 15 degrees<span />

Travka [436]

Answer:

You can calculate net change by subtracting the current day's closing price for an asset from the closing price of the previous day!

Step-by-step explanation:

(What net change is) The net change theorem states that when a quantity changes, the final value equals the initial value plus the integral of the rate of change. Net change can be a positive number, a negative number, or zero.

What would the answer be???

Korolek [52]

Answer:

The solution is obtained by adding the two equations.

The solution is: (x, y) = ( $- \frac{2}{3}$ , $- \frac{7}{3}$ )

Step-by-step explanation:

We are given two equations with two variables. The strategy is to eliminate one variable and solve for both the variables.

The two equations are:

$7x + y = - 7 \hspace{15mm} \hdots (1)$

$2x - y = 1 \hspace{15mm} \hdots (2)$

Adding both the equations, we get:

$7x + 2x + y - y = - 7 + 1$

$\implies 9x = - 6$

$\implies x = - \frac{2}{3}$

Substituting the value of 'x', we get the value of y.

We substitute in (2). [Can be substituted in any equation].

We get: y = 2x - 1

$\imples y = 2\bigg(\frac{-2}{3}\bigg) - 1$

$\implies -\frac{4}{3} - 1$

$\implies y = -\frac{7}{3}$

So, we get the corresponding values of x and y which is the solution of the two equations.
