Answer:
∠Q ≈ 42.969, ∠P ≈ 52.03, QR ≈ 15.036
Step-by-step explanation:
Law of sines:
13/sin Q = 19/sin 85°
=> sin Q = 13 × sin 85°/19
=> Q = sin^-1 (13 × sin 85°/19)
=> Q ≈ 42.969
∠P=> 180 - 85 - 42.969 ≈ 52.03
QR/sin 52.03° = 19/sin 85°
=> QR = sin 52.03° × 19/sin 85°
=> QR ≈ 15.036
Answer:
The number is 8.
Step-by-step explanation:
If the positive number is x then:
x^2 = 5x + 24
x^2 - 5x - 24 = 0
(x - 8)(x + 3) = 0
x =8, -3 .
x is positive so the answer is 8.
