Answer:

\fbox {P = 6.76 cm}

Step-by-step explanation:

<u>Finding the missing angle</u> :

  • 22° + ∠R + 72° = 180°
  • ∠R = 180° - 94°
  • ∠R = 86°

<u>Applying the Law of Sines</u> :

\boxed {\frac{sin P}{P} = \frac{sin R}{PQ}}

<u>Substituting the known values</u> :

  • sin 22° / P = sin 86° / 18
  • P = sin 22° × 18 / sin 86°
  • P = 0.374606593 × 18 / 0.99756405
  • P = 6.76 cm

2. Solve the following equations for 0° Sx &lt; 180°.
diamong [38]

Answer:

See below in bold.

Step-by-step explanation:

(1) cosec ( x + 10) = 3

Now cosec x = 1/sin x so

1 / sin (x + 10) = 3

3 sin (x + 10) = 1

sin (x + 10) = 1/3

x + 10 = 19.47 , 160.53 degrees

x = 9.47, 150.53 degrees.

(ii) cot (x - 30) =0.45

cot (x - 30)= 1 /tan (x- 30) so we have

tan (x - 30) = 1 / 0.45 = 2.2222

x - 30 = 65.77 degrees

x = 95.77 degrees.

2:x:4

Lana Omar and George

Omar's share is 10 JD

22-10 is 12

2x+4x=12

6x=12

x=2

So put the ratio to

4:2x:8

x=5
