Answer:

a. x > 9

Step-by-step explanation:

7 - 2/3x < x - 8

Add 2/3 x to each side

7 - 2/3x+ 2/3 x < x+ 2/3 x - 8

7 < x + 2/3 x -8

Add 8 to each side

7+8 < x + 2/3 x -8+8

15 < x + 2/3 x

Get a common denominator for x of 3

15 < 3/3 x + 2/3 x

15 < 5/3 x

Multiply by 3/5 to isolate x

3/5 * 15 < 5/3x * 3/5

9 < x

Quadrilateral STWR is inscribed inside a circle as shown below. Write a proof showing that angles T and R are supplementary.

AlladinOne [14]

Observe the given figure.

Here, angle T and R are the inscribed angles.

And sum of inscribed angles is half of measure of intercepted arcs.

Since, the measure of intercepted arcs is 360 degrees.

Therefore, $\angle T + \angle R = \frac{1}{2} \times 360 ^{\circ}$

$\angle T + \angle R = 180 ^{\circ}$

Hence, the sum of the two angles is 180 degrees.

Therefore, these are the supplementary angles.

Therefore, angle T and angle R are supplementary angles.

Hence, proved.
