The answer is 10 2/11. I hope this helps!
You just add up all the sides.
3.2 + 3.2 + 3.2 + 4.88 + 0.6
6.4 + 3.2 + 4.88 + 0.6
9.6 + 4.88 + 0.6
14.48 + 0.6
15.08
The perimeter is 15.08.
Hope this helps! :D
Answer:
37) m∠x = 5.25
39) m∠x = 0.5236 and m∠x = 2.62
Step-by-step explanation:
37)
∵ cotx = -0.6 and 3π/2 ≤ x ≤ 2π
∴ tanx = -1/0.6
∵ ∠ x in the fourth quadrant ⇒ ∴ m∠x = 2π - α where α is an acute angle
∵ tanα = 1/0.6 ⇒ α =
∴ α = 1.03038
∴ m∠x = 2π - 1.03038 = 5.25
39)
∵ cscx = 2 and 0 ≤ x ≤ 2π
∴ sinx = 1/2 ⇒ +ve value
∴ ∠x is in the first quadrant or the second quadrant
∴ m∠x = α or m∠x = π - α
∵ sinα = 1/2 ⇒ ∴ α =
∴ α = 0.5236
∴ m∠x = 0.5236
∴ m∠x = π - 0.5236 = 2.6216 ≅ 2.62
Answer:
30.2 - 13.7=n
Step-by-step explanation:
To get how far he ran you have to subtract 30.2 from 13.7 therefore giving you 16.5 which will be the total distance he ran after lunch.
