Answer:
1596.2 ft/m
Step-by-step explanation:
<u>Data</u>
- height of water, h = 11 ft
- acceleration of gravity, g = 32.17 ft/s²
Given that 60 seconds are equivalent to 1 minute:
g = 32.17 ft/s² * 60² s²/1 min² = 115812 ft/min²
From Bernoulli's theorem:
velocity = √(2gh)
velocity = √(2*115812*11)
velocity = 1596.2 ft/m
Answer:
Step-by-step explanation:
Given: quadrilateral ABCD inscribed in a circle
To Prove:
1. ∠A and ∠C are supplementary.
2. ∠B and ∠D are supplementary.
Construction : Join AC and BD.
Proof: As, angle in same segment of circle are equal.Considering AB, BC, CD and DA as Segments, which are inside the circle,
∠1=∠2-----(1)
∠3=∠4-----(2)
∠5=∠6-------(3)
∠7=∠8------(4)
Also, sum of angles of quadrilateral is 360°.
⇒∠A+∠B+∠C+∠D=360°
→→∠1+∠2+∠3+∠4+∠5+∠6+∠7+∠8=360°→→→using 1,2,3,and 4
→→→2∠1+2∠4+2∠6+2∠8=360°
→→→→2( ∠1 +∠6) +2(∠4+∠8)=360°⇒Dividing both sides by 2,
→→→∠B + ∠D=180°as, ∠1 +∠6=∠B , ∠4+∠8=∠B------(A)
As, ∠A+∠B+∠C+∠D=360°
∠A+∠C+180°=360°
∠A+∠C=360°-180°------Using A
∠A+∠C=180°
Hence proved.

The answer is B.
Hope it helps!
3x^2=375
x^2=125
x=11.18
c or d, they say the same thing
It’s 60 degrees
Ex: the total number when the degrees is added together should be 180
