Answer:

a) $x = 9$

b) $m \angle 1 = m \angle 2 = 54^\circ$

Step-by-step explanation:

Since $r\ ||\ s$ , through the Alternate Angle Theorem, $m \angle 1 = m \angle 2$ . We can solve for x by setting up an equation where both angles are equal to each other:

$m \angle 1 = m \angle 2\\63-x = 72-2x\\63 +x = 72\\x = 9$

Now plug in x for both of the formulas to get their angles:

$m \angle 1 = (63 - x)^\circ = (63-9)^\circ = 54^\circ$ $m \angle 2 = (72-2x)^\circ = (72-2(9))^\circ = (72-18)^\circ = 54^\circ$

George is comparing two different phones. The screen of phone A has a width of 5.3 cm. The width of the screen on phone B

Answer:

To answer this question, you need to makes the unit of the smartphone screen same. In this case, phone A is using decimal and phone B is using a fraction. You can use which was easier.

Let's try to use decimal. Then you need to convert phone B fraction width into decimal width. The calculation would be: 5cm + 1/3cm= 5 cm + 0.333cm= 5.333cm

From here it clear that phone B has a wider screen than phone A.
