The true statements are;

1) AB + BC = AC

Length of BC = |6 - 1|

2) ∠JMK = 50°

∠KML = 35°

<h3>How to Interpret Number Line intervals?</h3>

1) From the given number line interval, we can deduce the interpretation as follows;

AB + BC = AC

Length of BC = 5 units or |6 - 1|

Length of B = 3 Units

2) We can see that ∠JML is an angle triangle. Thus, ∠JML = 85°. Thus;

6x + 2 + 4x + 3 = 85

10x + 5 = 85

10x = 85 - 5

10x = 80

x = 80/10

x = 8°

Thus;

∠JMK = 6(8) + 2

∠JMK = 50°

∠KML = 85° - 50°

∠KML = 35°

For the reciprocal, you swap numerator and denominator.

a. The reciprocal of \frac{\sqrt{2}}{2} is \frac{2}{\sqrt{2}}
To rationalize the irrational denominator, multiply numerator and denominator by the radical, then simplify.
=\frac{2 \times \sqrt{2}}{\sqrt{2} \times \sqrt{2}} = \frac{2 \sqrt{2}}{2} = \sqrt{2}

b. \frac{-2}{\sqrt{3}} = \frac{-2 \sqrt{3}}{3}
