Answer:
<QRS= (10.x - 1) = (10.6 - 1) = 59°
Step-by-step explanation:
the triangle is not accurate but drawing one is truly useful in calculating. Besides, I don't know how it is called in English but it is something about the exterior angles (maybe)
I really hope this helps you
I would say... None.

Step-by-step explanation:
- <em>Exterior angle is same as sum of remote interior angles.</em>
- Solving for x in each case below.
<h3>
#7</h3>
- 5x + 10 + 58 = 11x + 2
- 5x + 68 = 11x + 2
- 11x - 5x = 68 - 2
- 6x = 66
- x = 11
<h3>#8</h3>
- 10x - 10 + 30 = 12x - 4
- 10x + 20 = 12x - 4
- 12x - 10x = 20 + 4
- 2x = 24
- x = 12
<h3>#9</h3>
- 46 - 1 + 8x = 18x + 5
- 8x + 45 = 18x + 5
- 18x - 8x = 45 - 5
- 10x = 40
- x = 4
<h3>#10</h3>
- 15x + 5 + 22x + 4 = 120
- 37x + 9 = 120
- 37x = 111
- x = 3
