Answer:

$5.10

Step-by-step explanation:

Irene pays with a $20 bill

Subtract all other values from $20

$20 - $10.66 - $4.22

$5.12

Round to the nearest dime, which is every $0.10

2 rounds down, so the final answer is $5.10

Hope this helps :)

In the diagram below, AB and TC are tangent to 0. Which equation could be solved to find x, the measure of AC?
LekaFEV [45]

The  equation that could be solved to find x, the measure of AC is 58 = 1/2(238 -x)

<h3>Circle theorem</h3>

The given diagram shows two intersecting lines tangential to a circle at points A and C.

Using the theorem that states, the measure of the angle at the vertex is equal to the half of the difference of the measure of the intercepted arcs.

Mathematically;

<B = 1/2(arcADC - arcAC)

58 = 1/2(238 -x)

Hence the  equation that could be solved to find x, the measure of AC is 58 = 1/2(238 -x)
