Question

Please help me with this !!!

Answer 1

Explanation:

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

Answer 2

`\fbox {P = 6.76 cm}`

Explanation:

Finding the missing angle :

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

Applying the Law of Sines :

`\boxed {(sin P)/(P) = (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
