Answer:
length = 27
breadth = 16
Step-by-step explanation:
The equation to determine the perimeter of the rectangle is given as
6x-10=86
the solution to above is x=16
Hence one of the side is 16. The formula for perimeter is given as
P=2(l+b)
if b=x =16
and P=86
replacing them inthe formula for perimeter
86=2(l+16)
dividing both sides by 2 we get
43=16+l
subtracting 16 from both sides we get
27=l
Hence the length and breadth of the rectangle are 27 and 16 respectively
Answer:
120 tries
Step-by-step explanation:
You can try 5 different wires in the first connection.
Then you have 4 wires left, so you try 4 wires in the second connection. Remember, you are now trying 4 wires for each of the first 5, so up to here you already made 4 * 5 tries = 20 tries.
Next you try 3, then 2, then you have 1 left.
Number of tries: 5 * 4 * 3 * 2 * 1 = 120
Answer: 120 tries

Step-by-step explanation:
The correct answer should be letter b as in Bob and correct if I’m wrong sorry
Answer:
we should know that :
sin ( a + b ) = sin a * cos b + sin b cos a
For the given equation :
sin (π + q) = sin π * cos q + sin q * cos π
sin π = zero and cos π = -1
∴ sin (π + q) = 0 * cos q + sin q * (-1) = - sin q
<u>Another solution:</u>
The angle (π + q) lies in the third quarter ⇒ (1)
(π + q) and (-q) are supplementary angles ⇒ (2)
From (1) and (2)
sin(π + q) = -sin q
