Question

Please help me with this !!!

Answer 1

Answer:

Step-by-step explanation:

I assume that QP = 18 cm and m∠Q = 72°

Answer 2

Answer:

$\fbox {P = 6.76 cm}$

Step-by-step explanation:

Finding the missing angle :

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

Applying the Law of Sines :

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

Substituting the known values :

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