An **angle** is produced at the <u>point</u> where two or more lines<em> meet</em>. Thus the <u>value</u> of LP required in the question is approximately **14**.

Two<em> lines</em> are said to be <em>perpendicular</em> when a <u>measure</u> of the angle <u>between</u> them is a <em>right angle</em>. While <u>parallel</u> lines are lines that do not meet even when <u>extended</u> to <em>infinity</em>.

From the question, let the <u>length</u> of LP be represented by **x**.

Thus, from the given question, it can be <u>deduced </u>that;

LM ≅ PN = 20

KP = KN - PN

= 30 - 20

KP = 10

LP = x

Also,

<MLP is a right angle, so that;

< KLP = < KLM - <PLM

= 126 - 90

<KLP =

So that applying the Pythagoras theorem to triangle KLP, we have;

Tan θ =

Tan 36 =

x =

=

x = 13.765

Therefore the <em>side</em> LP ≅ 14.

I hope that's help:) Please rate

If you have any further questions please let me know.Thx

**Answer:**

**Step-by-step explanation:**

y - 21 = 1/7(x + 7)

y - 21 = 1/7x + 1

y = 1/7x + 22
