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
9x9=81
so there is 9 on 2 sides, which is 18 when it gets added together. DONT FORGET ABOUT THE OTHER 2 SIDES!! you have four sides of the square so 9x4=36. I believe the answer is actually 36

Answer: $19.60
Step-by-step explanation:
24.50 x 20% or (.20)= 4.90
24.50-4.90=19.60
$19.60 is the answer
Answer:
total area. 78m breadth.
Step-by-step explanation:
First, do 4 multiplied by 3 to find the area of one carpet. The answer is 12m. Then, do 12m multiplied by 23 to get the total area. The answer will be 276m squared. If you want to find width then do 3m multipled by 26 which is 78m.
