Step 1:

Cost of large cup = $5

Step 2:

Number of large David orders = 10 cups

A good plan to find the amount Jon spent is to find the number of large cups Jon orders from the number of large cups David orders.

Jon order 4 fewer large cups

Therefore,

Jon order = 6 cups

Step 3:

A good plan to find the amount Jon spent is to find the number of large cups Jon orders from the number of large cups David orders.

The amount Jon spent on coffee = 6 x $5 = $30

3 lines are shown. A line with points T, R, W intersects a line with points S, R, W at point R. Another line extends from point
Salsk061 [2.6K]

Given:

Consider the three point of second line are S, R, V instead of S, R, W.

A line with points T, R, W intersects a line with points S, R, V at point R. Another line extends from point R to point U between angle T, R, V.

\angle VRW=(3x)^\circ

\angle TRS=(2x+18)^\circ

To find:

The m∠SRW.

Solution:

The figure according to the given information is shown below (not to scale).

From the below figure it is clear that, \angle VRW and \angle TRS are vertically opposite angles. So, their measures are equal.

3x=2x+18

Subtract 2x from both sides.

3x-2x=18

x=18

Using x=18 the measure of angle VRW is

\angle VRW=(3x)^\circ

\angle VRW=(3\times 18)^\circ

\angle VRW=54^\circ

Now,

\angle VRW+\angle SRW=180^\circ       [Linear pair]

54^\circ+\angle SRW=180^\circ

\angle SRW=180^\circ-54^\circ

\angle SRW=126^\circ

Therefore, the correct option is C.

The formula for the sum of the degree measures of the interior angles of a polygon is S= 180(n-2). Solve for n, the number of si
kolbaska11 [484]

Answer:

n = S/180 + 2

Step-by-step explanation:

S = 180(n - 2)

First, divide both sides by 180.

S/180 = n - 2

Now add 2 to both sides.

S/180 + 2 = n

n = S/180 + 2
