<h3><u>Answer</u> :</h3>
For triangle : A + B + C = π
⇒ A + B = π - C
⇒ cot(A + B) = cot(π - C)
⇒
⇒
<u>Now 1st part of the given expression</u>!
⇒
⇒
⇒
⇒ 1 - cotB cotC
<u>Similarly 2nd part</u>!
⇒ 1 - cotA cotB
<u>Similarly 3rd part</u>!
⇒ 1 - cotC cotA
<u>LHS</u> :
= <u>RHS</u>
<h3>Hence Proved!!</h3>
Answer:
Step-by-step explanation:
The deceleration experimented by the car is the product of kinetic coefficient of friction and gravitational constant:
The initial speed is computed from the following kinematic expression:
1)
23.55+23.55×0.028
=24.21
2)
The formula is
A=p (1+rt)
A future value?
P present value 400
R interest rate 0.036
T time 5years
A=400×(1+0.036×5)
A=472
3)
((2.25−1.8)÷1.8)×100=25%
