Answer:
69.6 ft
Step-by-step explanation:
The arc length can be found as a fraction of the circumference. That fraction is the ratio of the central angle measure to the measure for the whole circle.
__
Central angle of remaining arc:
360° -150° = 210°
Fraction of full circumference:
210°/360° = 7/12
The circumference of the circle is ...
C = 2πr = 2π(19 ft) = 38π ft.
Then the length of the remaining arc is ...
(7/12)(38π) ft ≈ 69.6 ft
The answer is <span>c. 25
</span>
<span>sin(ϴ + 15) = cos(2ϴ)
</span>sin(ϴ + 15) =sin(25 + 15) =<span>sin(40) =0.64
</span>cos(2ϴ)=cos(2x25)=<span>cos(50)=0.64
</span> so <span>ϴ=25</span>
Answer:
1 mile
Step-by-step explanation:
1m =160934 cm
The answer will be 17/4 or 4 1/4. Hope it help!
3m - 4n - 8 = 3m + (-4n) + (-8)
