Answer:

<u>Please read the answers below.</u>

Step-by-step explanation:

Let's recall that in a square all its sides are equal length and all the four internal angles measure 90 °

5. If LN = 46, then we have:

OM = <u>46</u> (Same length than LN)

PN = LN/2 = 46/2 = <u>23</u>

ON = √LN²/2 = √ 46²/2 = √ 2,116/2 = √ 1,058 = <u>32.53 (Rounding to two decimal places)</u>

MN = ON = <u>32.53</u>

6. m ∠EFG = <u>90°</u>

m ∠GDH = ∠GDH/2 = 90/2 =<u> 45°</u>

m ∠FEG = ∠DEF/2 = 90/2 =<u> 45°</u>

m ∠DHG = 180 - (∠GDH + ∠DGH) = 180 - (45 + 45)= 180 - 90 = <u>90</u>°

7. Solve for x

6x - 21 = ∠PQR/2

6x - 21 = 90/2

6x - 21 = 45

6x = 45 +21

6x = 66

<u>x = 11</u>
