Answer:
QR = 65.4 m
Step-by-step explanation:
a. Apply Law of Cosines to find QR:
p² = q² + r² - 2qr × Cos P
p = QR = ?
q = PR = 150 m
r = PQ = 120 m
P = 25°
Plug in the values
p² = 150² + 120² - (2)(150)(120) × Cos(25°)
p² = 22,500 + 14,400 - 36,000 × 0.9063
p² = 36,900 - 32,626.8
p² = 4,273.2
p = √4,273.2
p ≈ 65.4 m (nearest tenth)
QR = 65.4 m
Answer:
70°
Step-by-step explanation:
The minor angle of AB forms a straight line with angle x. When summed up it equals 180°.
minor angle of AB + x° = 180°
110° + x° = 180°
x° = 180° - 110°
= 70°
Enjoy!!!
Answer:
Is that Deltamath?
Step-by-step explanation:
The answer would be 42 because its the same angle as the other one
